In this work, we have introduced a scalable dry-transfer approach for 2D-TMDCs grown by MOCVD (metal-organic chemical vapor deposition) on sapphire. Transfer to a silicon/silicon dioxide (Si/SiO$_2$) substrate is performed using PMMA (poly(methyl methacrylate)) and TRT (thermal release tape) as sacrificial layer and carrier, respectively. Our proposed method ensures a reproducible peel-off from the growth substrate and better preservation of the 2D-TMDC during PMMA removal in solvent, without compromising its adhesion to the target substrate. A comprehensive comparison between the dry method introduced in this work and a standard wet transfer based on potassium hydroxide (KOH) solution shows improvement in terms of cleanliness and structural integrity for dry-transferred layer, as evidenced by X-ray photoemission and Raman spectroscopy, respectively. Moreover, fabricated field-effect transistors (FETs) demonstrate improvements in subthreshold slope, maximum drain current and device-to-device variability. The dry-transfer method developed in this work enables large-area integration of 2D-TMDC layers into (opto)electronic components with high reproducibility, while better preserving the as-grown properties of the layers. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2412.02407v1-abstract-full').style.display = 'none'; document.getElementById('2412.02407v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 3 December, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> December 2024. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">29 pages</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2403.19190">arXiv:2403.19190</a> <span> [<a href="https://arxiv.org/pdf/2403.19190">pdf</a>, <a href="https://arxiv.org/format/2403.19190">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Materials Science">cond-mat.mtrl-sci</span> </div> </div> <p class="title is-5 mathjax"> Prediction and identification of point defect fingerprints in the X-ray photoelectron spectra of TiN$_x$ </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/cond-mat?searchtype=author&query=Ondra%C4%8Dka%2C+P">Pavel Ondra膷ka</a>, <a href="/search/cond-mat?searchtype=author&query=K%C3%BCmmerl%2C+P">Pauline K眉mmerl</a>, <a href="/search/cond-mat?searchtype=author&query=Hans%2C+M">Marcus Hans</a>, <a href="/search/cond-mat?searchtype=author&query=Mr%C3%A1z%2C+S">Stanislav Mr谩z</a>, <a href="/search/cond-mat?searchtype=author&query=Primetzhofer%2C+D">Daniel Primetzhofer</a>, <a href="/search/cond-mat?searchtype=author&query=Holec%2C+D">David Holec</a>, <a href="/search/cond-mat?searchtype=author&query=Va%C5%A1ina%2C+P">Petr Va拧ina</a>, <a href="/search/cond-mat?searchtype=author&query=Schneider%2C+J+M">Jochen M.

X-ray photoelectron spectroscopy (XPS) measurements of Ti-deficient TiN films reveal additional N 1s spectral components at lower binding energies. Ab initio calculations predict that these components are caused by either Ti vacancies, which induce a N 1s BE shift of $-0.53$ eV in its first N neighbors, and/or N tetrahedral interstitials, which have their N 1s BE shifted by $-1.18$ eV and also shift BE of their first N neighbors by $-0.53$ eV. However, the {\it ab initio} calculations also reveal that the tetrahedral N interstitial is unstable at room temperature. We, therefore, unambiguously attribute the detected signal to Ti vacancies. Furthermore, the vacancy concentration in Ti-deficient TiN was quantified with XPS supported by ab initio calculations. The largest BE shifts of $-1.53$, $-1.80$ and $-2.28$ eV for Ti 2p$_{3/2}$ electrons are predicted for the Ti tetrahedral, split (10$\overline{1}$)-aligned and split (111)-aligned interstitial atoms, respectively, and we, therefore, propose XPS could detect them. Other defects such as N vacancy or N split (10$\overline{1}$)-aligned interstitial introduce smaller N 1s and Ti 2p$_{3/2}$ BE shifts and are unlikely to be detectable experimentally. Our work highlights the potential of ab initio-guided XPS measurements in detecting and quantifying point defects in $B$1 TiN. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2403.19190v1-abstract-full').style.display = 'none'; document.getElementById('2403.19190v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 28 March, 2024; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> March 2024. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2312.12235">arXiv:2312.12235</a> <span> [<a href="https://arxiv.org/pdf/2312.12235">pdf</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Materials Science">cond-mat.mtrl-sci</span> </div> </div> <p class="title is-5 mathjax"> On the role of Grain Boundary Character in the Stress Corrosion Cracking of Nanoporous Gold Thin Films </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/cond-mat?searchtype=author&query=Saksena%2C+A">Aparna Saksena</a>, <a href="/search/cond-mat?searchtype=author&query=El-Zoka%2C+A">Ayman El-Zoka</a>, <a href="/search/cond-mat?searchtype=author&query=Saxena%2C+A">Alaukik Saxena</a>, <a href="/search/cond-mat?searchtype=author&query=Hatipoglu%2C+E">Ezgi Hatipoglu</a>, <a href="/search/cond-mat?searchtype=author&query=Schneider%2C+J+M">Jochen M.

NPG thin films can offer ease of handling, better tunability of the chemistry and microstructure of the nanoporous structure, and represent a more sustainable usage of scarce resources. These films are however prone to intergranular cracking during dealloying, limiting their stability and potential applications. Here, we set out to systematically investigate the grain boundaries in Au28Ag72 thin films. We observe that a sample synthesized at 400 掳C is at least 2.5 times less prone to cracking compared to a sample synthesized at room temperature. This correlates with a higher density of coincident site lattice grain boundaries, especially the density of coherent sigma 3, increased, which appear resistant against cracking. Nanoscale compositional analysis of random high-angle grain boundaries reveals prominent Ag enrichment up to 77 at.%, whereas sigma 3 coherent twin boundaries show Au enrichment of up to 30 at.%. The misorientation and the chemistry of grain boundaries hence affect their dealloying behavior, which in turn controls the cracking, and the possible longevity of NPG thin films for application in electrocatalysis. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2312.12235v1-abstract-full').style.display = 'none'; document.getElementById('2312.12235v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 19 December, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> December 2023. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2305.17539">arXiv:2305.17539</a> <span> [<a href="https://arxiv.org/pdf/2305.17539">pdf</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Materials Science">cond-mat.mtrl-sci</span> </div> </div> <p class="title is-5 mathjax"> Valence electron concentration- and N vacancy-induced elasticity in cubic early transition metal nitrides </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/cond-mat?searchtype=author&query=Aghda%2C+S+K">Soheil Karimi Aghda</a>, <a href="/search/cond-mat?searchtype=author&query=Bogdanovski%2C+D">Dimitri Bogdanovski</a>, <a href="/search/cond-mat?searchtype=author&query=Loefler%2C+L">Lukas Loefler</a>, <a href="/search/cond-mat?searchtype=author&query=Sua%2C+H+H">Heng Han Sua</a>, <a href="/search/cond-mat?searchtype=author&query=Patterer%2C+L">Lena Patterer</a>, <a href="/search/cond-mat?searchtype=author&query=Holzapfel%2C+D+M">Damian M.

The DFT results indicate that the elastic behavior of the TMNx depends on both the N-vacancy concentration and the valence electron concentration (VEC) of the transition metal: While TiNx and ZrNx exhibit vacancy-induced reductions in elastic modulus, VNx and NbNx show an increase. These trends can be rationalized by considering vacancy-induced changes in elastic anisotropy and bonding. While introduction of N-vacancies in TiNx results in a significant reduction of elastic modulus along all directions and a lower average bond strength of Ti-N, the vacancy-induced reduction in [001] direction of VNx is overcompensated by the higher stiffness along [011] and [111] directions, resulting in a higher average bond strength of V-N. To validate the predicted vacancy-induced changes in elasticity experimentally, close-to-single-crystal VNx (0.77<x<0.97) are grown on MgO(001) substrates. As the N-content is reduced, the relaxed lattice parameter a0, as probed by X-ray diffraction, decreases from 4.128 A to 4.096 A. This reduction in lattice parameter is accompanied by an anomalous 11% increase in elastic modulus, as determined by nanoindentation. As the experimental data agree with the predictions, the elasticity enhancement in VNx upon N-vacancy formation can be understood based on the concomitant changes in elastic anisotropy and bonding. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2305.17539v1-abstract-full').style.display = 'none'; document.getElementById('2305.17539v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 27 May, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> May 2023. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">30 pages, 8 figures in the manuscript, 1 figure in supplementary materials</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2305.17459">arXiv:2305.17459</a> <span> [<a href="https://arxiv.org/pdf/2305.17459">pdf</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Applied Physics">physics.app-ph</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Materials Science">cond-mat.mtrl-sci</span> </div> </div> <p class="title is-5 mathjax"> Large-area deposition of protective (Ti,Al)N coatings onto polycarbonate </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/cond-mat?searchtype=author&query=Patterer%2C+L">Lena Patterer</a>, <a href="/search/cond-mat?searchtype=author&query=Kollmann%2C+S">Sabrina Kollmann</a>, <a href="/search/cond-mat?searchtype=author&query=Arcos%2C+T+d+l">Teresa de los Arcos</a>, <a href="/search/cond-mat?searchtype=author&query=Jende%2C+L">Leonie Jende</a>, <a href="/search/cond-mat?searchtype=author&query=Aghda%2C+S+K">Soheil Karimi Aghda</a>, <a href="/search/cond-mat?searchtype=author&query=Holzapfel%2C+D+M">Damian M.

These differences present formidable challenges for the deposition process development as low-temperature synthesis routes have to be explored to avoid a thermal overload of the polymer substrate. Here, a large-area sputtering process is developed to address the challenges by systematically adjusting target peak power density and duty cycle. Adhering (Ti,Al)N coatings with a critical residual tensile stress of 2.2 +/- 0.2 GPa are obtained in the pulsed direct current magnetron sputtering range, whereas depositions at higher target peak power densities, realized by high power pulsed magnetron sputtering, lead to stress-induced adhesive and/or cohesive failure. The stress-optimized (Ti,Al)N coatings deposited onto PC with a target peak power density of 0.036 kW cm-2 and a duty cycle of 5.3% were investigated by cross-cut test confirming adhesion. By investigating the bond formation at the PC | (Ti,Al)N interface, mostly interfacial CNx bonds and a small fraction of (C-O)-(Ti,Al) bonds are identified by X-ray photoelectron spectroscopy, indicating reactions at the hydrocarbon and the carbonate groups during deposition. Nanoindentation reveals an elastic modulus of 296 +/- 18 GPa for the (Ti,Al)N coating, while a Ti-Al-O layer is formed during electrochemical impedance spectroscopy in a borate buffer solution, indicating protective passivation. This work demonstrates that the challenge posed by the extremely different material properties at the interface of soft polymer substrates and hard coatings can be addressed by systematical variation of the pulsing parameters to reduce the residual film stress. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2305.17459v1-abstract-full').style.display = 'none'; document.getElementById('2305.17459v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 27 May, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> May 2023. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2305.17430">arXiv:2305.17430</a> <span> [<a href="https://arxiv.org/pdf/2305.17430">pdf</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Materials Science">cond-mat.mtrl-sci</span> </div> </div> <p class="title is-5 mathjax"> Bond formation at polycarbonate | X interfaces (X = Al$_2$O$_3$, TiO$_2$, TiAlO$_2$) studied by theory and experiments </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/cond-mat?searchtype=author&query=Patterer%2C+L">Lena Patterer</a>, <a href="/search/cond-mat?searchtype=author&query=Ondra%C4%8Dka%2C+P">Pavel Ondra膷ka</a>, <a href="/search/cond-mat?searchtype=author&query=Bogdanovski%2C+D">Dimitri Bogdanovski</a>, <a href="/search/cond-mat?searchtype=author&query=Mr%C3%A1z%2C+S">Stanislav Mr谩z</a>, <a href="/search/cond-mat?searchtype=author&query=P%C3%B6llmann%2C+P+J">Peter J.

Generally, the predicted bond formation is consistent with the experimental data. For all three interfaces, the majority of bonds identified by XPS are (C-O)-metal bonds, whereas C-metal bonds are the minority. Compared to the PC | Al$_2$O$_3$ interface, the PC | TiO$_2$ and PC | TiAlO$_2$ interfaces exhibit a reduction in the measured interfacial bond density by ~ 75 and ~ 65%, respectively. Multiplying the predicted bond strength with the corresponding experimentally determined interfacial bond density shows that Al$_2$O$_3$ exhibits the strongest interface with PC, while TiO$_2$ and TiAlO$_2$ exhibit ~ 70 and ~ 60% weaker interfaces, respectively. This can be understood by considering the complex interplay between the metal oxide composition, the bond strength as well as the population of bonds that are formed across the interface. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2305.17430v1-abstract-full').style.display = 'none'; document.getElementById('2305.17430v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 27 May, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> May 2023. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2305.16715">arXiv:2305.16715</a> <span> [<a href="https://arxiv.org/pdf/2305.16715">pdf</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Materials Science">cond-mat.mtrl-sci</span> </div> </div> <p class="title is-5 mathjax"> Correlative Theoretical and Experimental Study of the Polycarbonate | X Interfacial Bond Formation (X = AlN, TiN, TiAlN) during Magnetron Sputtering </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/cond-mat?searchtype=author&query=Patterer%2C+L">Lena Patterer</a>, <a href="/search/cond-mat?searchtype=author&query=Ondra%C4%8Dka%2C+P">Pavel Ondra膷ka</a>, <a href="/search/cond-mat?searchtype=author&query=Bogdanovski%2C+D">Dimitri Bogdanovski</a>, <a href="/search/cond-mat?searchtype=author&query=Mr%C3%A1z%2C+S">Stanislav Mr谩z</a>, <a href="/search/cond-mat?searchtype=author&query=Aghda%2C+S+K">Soheil Karimi Aghda</a>, <a href="/search/cond-mat?searchtype=author&query=P%C3%B6llmann%2C+P+J">Peter J.

The simulations predict significant differences at the interface, as N and Ti form bonds with all functional groups of the polymer, while Al reacts selectively only with the carbonate group of pristine PC. In good agreement with simulations, experimental data reveal that the PC | AlN and the PC | TiAlN interfaces are mainly defined by interfacial C-N bonds, whereas for PC | TiN, the interface formation is also characterized by numerous C-Ti and (C-O)-Ti bonds. Bond strength calculations combined with the measured interfacial bond density indicate the strongest interface for PC | TiAlN followed by PC | AlN, whereas the weakest is predicted for PC | TiN due to its lower density of strong interfacial C-N bonds. This study shows that the employed computational strategy enables prediction of the interfacial bond formation between PC and metal nitrides and that it is reasonable to assume that the research strategy proposed herein can be readily adapted to other organic | inorganic interfaces. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2305.16715v1-abstract-full').style.display = 'none'; document.getElementById('2305.16715v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 26 May, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> May 2023. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2303.10266">arXiv:2303.10266</a> <span> [<a href="https://arxiv.org/pdf/2303.10266">pdf</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Materials Science">cond-mat.mtrl-sci</span> </div> </div> <p class="title is-5 mathjax"> On the determination of the thermal shock parameter of MAX phases: A combined experimental-computational study </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/cond-mat?searchtype=author&query=Fekete%2C+M">Matej Fekete</a>, <a href="/search/cond-mat?searchtype=author&query=Azina%2C+C">Clio Azina</a>, <a href="/search/cond-mat?searchtype=author&query=Ondra%C4%8Dka%2C+P">Pavel Ondra膷ka</a>, <a href="/search/cond-mat?searchtype=author&query=L%C3%B6fler%2C+L">Lukas L枚fler</a>, <a href="/search/cond-mat?searchtype=author&query=Bogdanovski%2C+D">Dimitri Bogdanovski</a>, <a href="/search/cond-mat?searchtype=author&query=Primetzhofer%2C+D">Daniel Primetzhofer</a>, <a href="/search/cond-mat?searchtype=author&query=Hans%2C+M">Marcus Hans</a>, <a href="/search/cond-mat?searchtype=author&query=Schneider%2C+J+M">Jochen M.

Here, the thermo-mechanical properties required for the calculation of RT are quantum-mechanically predicted, experimentally determined, and compared for Ti3AlC2 and Cr2AlC MAX phases. The coatings are synthesized utilizing direct current magnetron sputtering without additional heating, followed by vacuum annealing. It is shown that the RT of both Ti3AlC2 and Cr2AlC obtained via simulations are in good agreement with the experimentally obtained ones. Comparing the MAX phase coatings, both experiments and simulations indicate superior thermal shock behavior of Ti3AlC2 compared to Cr2AlC, attributed primarily to the larger linear coefficient of thermal expansion of Cr2AlC.

We present a combined experimental and modelling approach to scope and build phase diagrams for defects. The discovery was enabled by triggering phase transformations of individual defects through local alloying, and sequentially imaging the structural and chemical changes using atomic-resolution scanning transmission electron microscopy. By observing atomic-scale phase transformations of a Mg grain boundary through Ga alloying, we exemplified the method to construct a grain boundary phase diagram using ab initio simulations and thermodynamic principles.

Atom probe specimens were prepared conventionally in a Ga focused ion beam (FIB) as well as a Xe plasma FIB in a cryogenic setup and subsequently cleaned in the atom probe to remove surface contamination before oxidation. While thermal energy input from the laser and longer atmospheric exposure time increased the measured hydrogen content in the specimen's apex region, cryo preparation revealed, that the hydrogen uptake in magnesium is independent of the employment of conventional or cryogenic FIB preparation. TEM measurements demonstrated the growth of a (111) MgO oxide layer with 3-4 nm thickness on the basal (0001) plane of the Mg atom probe specimen. APT data further revealed the formation of an aluminum-rich region between bulk Mg and the native oxide. The aluminum enrichment of up to ~20 at.% at the interface is consistent with an inward growth of the oxide scale. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2303.07763v3-abstract-full').style.display = 'none'; document.getElementById('2303.07763v3-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 2 June, 2023; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 14 March, 2023; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> March 2023. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2303.04480">arXiv:2303.04480</a> <span> [<a href="https://arxiv.org/pdf/2303.04480">pdf</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Materials Science">cond-mat.mtrl-sci</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.3390/ma16062417">10.3390/ma16062417 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> CALPHAD-based modelling of the temperature-composition-structure relationship during physical vapor deposition of Mg-Ca thin films </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/cond-mat?searchtype=author&query=Keuter%2C+P">Philipp Keuter</a>, <a href="/search/cond-mat?searchtype=author&query=Baben%2C+M+t">Moritz to Baben</a>, <a href="/search/cond-mat?searchtype=author&query=Aliramaji%2C+S">Shamsa Aliramaji</a>, <a href="/search/cond-mat?searchtype=author&query=Schneider%2C+J+M">Jochen M.

While direct high-temperature synthesis resulted in multiphase films, as evidenced by X-ray diffraction analyses, room temperature depositions, followed by annealing to 760 掳C led to the formation of phase pure (Cr,Y)2AlC by diffusion. Higher annealing temperatures caused decomposition of the metastable phase into Cr2AlC, Y5Al3 , and Cr-carbides. In contrast to pure Cr2AlC, the Y-containing phase crystallizes directly in the MAX phase structure instead of first forming a disordered solid solution. Furthermore, the crystallization temperature was shown to be Y-content dependent and was increased by ~200 掳C for 5 at.% Y compared to Cr2AlC. Calculations predicting the metastable phase formation of (Cr,Y)2AlC and its decomposition are in excellent agreement with the experimental findings. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2209.07119v1-abstract-full').style.display = 'none'; document.getElementById('2209.07119v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 15 September, 2022; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> September 2022. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">submitted to Journal of the American Ceramic Society, 9 Figures, 30 pages total</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2111.04606">arXiv:2111.04606</a> <span> [<a href="https://arxiv.org/pdf/2111.04606">pdf</a>, <a href="https://arxiv.org/format/2111.04606">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Materials Science">cond-mat.mtrl-sci</span> </div> </div> <p class="title is-5 mathjax"> Microstructure, grain boundary evolution and anisotropic Fe segregation in (0001) textured Ti thin films </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/cond-mat?searchtype=author&query=Devulapalli%2C+V">Vivek Devulapalli</a>, <a href="/search/cond-mat?searchtype=author&query=Hans%2C+M">Marcus Hans</a>, <a href="/search/cond-mat?searchtype=author&query=Sukumar%2C+P+T">Prithiv T.

Faceting and solute segregation to minimize the GB energy is a commonly observed phenomenon. In this paper, a deposition process to obtain pure tilt GBs in titanium (Ti) thin films is presented. By increasing the power density, a transition from polycrystalline film growth to a maze bicrystalline Ti film on SrTiO$_3$ (001) substrate is triggered. All the GBs in the bicrystalline thin film are characterized to be $危$13 [0001] coincident site lattice (CSL) boundaries. The GB planes are seen to distinctly facet into symmetric {$\bar{7}520$} and asymmetric {$10\bar{1}0$} // {$11\bar{2}0$} segments of 20-50~nm length. Additionally, EDS reveals preferential segregation of iron (Fe) in every alternate symmetric {$\bar{7}520$} segment. Both the faceting and the segregation are explained by a difference in the CSL density between the facet planes. Furthermore, in the GB plane containing Fe segregation, atom probe tomography is used to experimentally determine the GB excess solute to be 1.25~atoms/nm$^{2}$. In summary, the study reveals for the first time a methodology to obtain bicrystalline Ti thin films with strong faceting and anisotropy in iron (Fe) segregation behaviour within the same family of planes. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2111.04606v1-abstract-full').style.display = 'none'; document.getElementById('2111.04606v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 8 November, 2021; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> November 2021. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">13 pages, 9 figures</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2110.03981">arXiv:2110.03981</a> <span> [<a href="https://arxiv.org/pdf/2110.03981">pdf</a>, <a href="https://arxiv.org/format/2110.03981">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Materials Science">cond-mat.mtrl-sci</span> </div> </div> <p class="title is-5 mathjax"> $\textit{Ab initio}$-guided X-ray photoelectron spectroscopy quantification of Ti vacancies in Ti$_{1-未}$O$_x$N$_{1-x}$ thin films </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/cond-mat?searchtype=author&query=Ondra%C4%8Dka%2C+P">Pavel Ondra膷ka</a>, <a href="/search/cond-mat?searchtype=author&query=Hans%2C+M">Marcus Hans</a>, <a href="/search/cond-mat?searchtype=author&query=Holzapfel%2C+D+M">Damian M.

It was shown, that the presence of a Ti vacancy reduces the 1s core electron binding energy of the first N neighbors by $\sim$0.6 eV and that this effect is additive with respect to the number of vacancies. Hence it is predicted that the Ti vacancy concentration can be revealed from the intensity of the shifted components in the N 1s core spectra region. This notion was critically appraised by fitting the N 1s region obtained via X-ray photoelectron spectroscopy (XPS) measurements of Ti$_{1-未}$O$_x$N$_{1-x}$ thin films deposited by high power pulsed magnetron sputtering. A model to quantify the Ti vacancy concentration based on the intensity ratio between the N 1s signal components, corresponding to N atoms with locally different Ti vacancy concentration, was developed. Herein a random vacancy distribution was assumed and the influence of surface oxidation from atmospheric exposure after deposition was considered. The so estimated vacancy concentrations are consistent with a model calculating the vacancy concentration based on the O concentrations determined by elastic recoil detection analysis and text book oxidation states and hence electroneutrality. Thus, we have unequivocally established that the formation and population of Ti vacancies in cubic Ti$_{1-未}$O$_x$N$_{1-x}$ thin films can be quantified by XPS measurements from N 1s core electron binding energy shifts. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2110.03981v2-abstract-full').style.display = 'none'; document.getElementById('2110.03981v2-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 22 October, 2021; <span class="has-text-black-bis has-text-weight-semibold">v1</span> submitted 8 October, 2021; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> October 2021. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2108.10053">arXiv:2108.10053</a> <span> [<a href="https://arxiv.org/pdf/2108.10053">pdf</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Materials Science">cond-mat.mtrl-sci</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Applied Physics">physics.app-ph</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1016/j.matchar.2021.111234">10.1016/j.matchar.2021.111234 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Early stages of dissolution corrosion in 316L and DIN 1.4970 austenitic stainless steels with and without anticorrosion coatings in static liquid lead-bismuth eutectic (LBE) at 500$^\circ$C </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/cond-mat?searchtype=author&query=Charalampopoulou%2C+E">Evangelia Charalampopoulou</a>, <a href="/search/cond-mat?searchtype=author&query=Lambrinou%2C+K">Konstantina Lambrinou</a>, <a href="/search/cond-mat?searchtype=author&query=Van+der+Donck%2C+T">Tom Van der Donck</a>, <a href="/search/cond-mat?searchtype=author&query=Paladino%2C+B">Boris Paladino</a>, <a href="/search/cond-mat?searchtype=author&query=Di+Fonzo%2C+F">Fabio Di Fonzo</a>, <a href="/search/cond-mat?searchtype=author&query=Azina%2C+C">Clio Azina</a>, <a href="/search/cond-mat?searchtype=author&query=Eklund%2C+P">Per Eklund</a>, <a href="/search/cond-mat?searchtype=author&query=Mr%C3%A1z%2C+S">Stanislav Mr谩z</a>, <a href="/search/cond-mat?searchtype=author&query=Schneider%2C+J+M">Jochen M.

The findings of this study provide recommendations on steel manufacturing with the aim of using the steels to construct Gen-IV lead-cooled fast reactors. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2108.10053v1-abstract-full').style.display = 'none'; document.getElementById('2108.10053v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 13 July, 2021; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> August 2021. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">52 pages, 22 figures, 4 tables</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Materials Characterization, Volume 178, 2021, 111234 </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/2005.01647">arXiv:2005.01647</a> <span> [<a href="https://arxiv.org/pdf/2005.01647">pdf</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Materials Science">cond-mat.mtrl-sci</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1016/j.corsci.2020.108704">10.1016/j.corsci.2020.108704 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Compatibility of $Zr_{2}AlC$ MAX phase-based ceramics with oxygen-poor, static liquid lead-bismuth eutectic </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/cond-mat?searchtype=author&query=Tunca%2C+B">Bensu Tunca</a>, <a href="/search/cond-mat?searchtype=author&query=Lapauw%2C+T">Thomas Lapauw</a>, <a href="/search/cond-mat?searchtype=author&query=Callaert%2C+C">Carolien Callaert</a>, <a href="/search/cond-mat?searchtype=author&query=Hadermann%2C+J">Joke Hadermann</a>, <a href="/search/cond-mat?searchtype=author&query=Delville%2C+R">Remi Delville</a>, <a href="/search/cond-mat?searchtype=author&query=Caspi%2C+E+N">El'ad N.

A new $Zr_{2}(Al,Bi,Pb)C$ MAX phase solid solution formed in-situ in the LBE-affected $Zr_{2}AlC$ grains. Out-of-plane ordering was favorable in the new solid solution, whereby $\textit{A}$-layers with high and low-Bi/Pb contents alternated in the crystal structure, in agreement with first-principles calculations. Bulk $Zr_{2}(Al,Bi,Pb)C$ was synthesized by reactive hot pressing to study the crystal structure of the solid solution by neutron diffraction. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('2005.01647v1-abstract-full').style.display = 'none'; document.getElementById('2005.01647v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 4 May, 2020; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> May 2020. </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/1305.4805">arXiv:1305.4805</a> <span> [<a href="https://arxiv.org/pdf/1305.4805">pdf</a>, <a href="https://arxiv.org/format/1305.4805">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Plasma Physics">physics.plasm-ph</span> <span class="tag is-small is-grey tooltip is-tooltip-top" data-tooltip="Materials Science">cond-mat.mtrl-sci</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1063/1.4819227">10.1063/1.4819227 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Bimodal substrate biasing to control 纬-Al2O3 deposition during reactive magnetron sputtering </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/cond-mat?searchtype=author&query=Prenzel%2C+M">Marina Prenzel</a>, <a href="/search/cond-mat?searchtype=author&query=Kortmann%2C+A">Annika Kortmann</a>, <a href="/search/cond-mat?searchtype=author&query=Stein%2C+A">Adrian Stein</a>, <a href="/search/cond-mat?searchtype=author&query=von+Keudell%2C+A">Achim von Keudell</a>, <a href="/search/cond-mat?searchtype=author&query=Nahif%2C+F">Farwah Nahif</a>, <a href="/search/cond-mat?searchtype=author&query=Schneider%2C+J+M">Jochen M.

Two series of absorption lines whose energy scales as sqrtB and B are present in the spectra and identified as contributions of massless holes at the H point and massive electrons in the vicinity of the K point, respectively. We find that the optical response of the K point electrons corresponds, over a wide range of energy and magnetic field, to a graphene bilayer with an effective inter-layer coupling 2纬_1, twice the value for a real graphene bilayer, which reflects the crystal ordering of bulk graphite along the c-axis.
