Our results show that increasing the width of Fibonacci’s wells of allows to the confinement of subminibands with a widening of minigaps, this causes a consistent and coherent fragmentation. The barrier thickness of Fibonacci bf acts on the width of subminibands by controlling the interaction force between neighboring eigenstates. Its increase gives rise to singularly extended states. The barrier height Fibonacci Vf permit to control the degree of structural disorder in these structures. The variation of these parameters permits the design of laser with modulated wavelength. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transmission%20coefficient%20%E2%80%93%20Quasiperiodic%20superlattices-%20singularly%20localized%20and%20extended%20states-%20structural%20parameters-%20Laser%20with%20modulated%20wavelength" title="transmission coefficient – Quasiperiodic superlattices- singularly localized and extended states- structural parameters- Laser with modulated wavelength">transmission coefficient – Quasiperiodic superlattices- singularly localized and extended states- structural parameters- Laser with modulated wavelength</a> </p> <a href="https://publications.waset.org/abstracts/39812/effect-of-the-structural-parameters-on-subbands-of-fibonacci-alxga1-xasgaas-superlattices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39812.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">378</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2274</span> Study of Quantum Lasers of Random Trimer Barrier AlxGa1-xAs Superlattices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bentata%20Samir">Bentata Samir</a>, <a href="https://publications.waset.org/abstracts/search?q=Bendahma%20Fatima"> Bendahma Fatima</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We have numerically studied the random trimer barrier AlxGa1-xAs superlattices (RTBSL).

The values of ideality factor (n), zero-bias barrier height (φB0), flat barrier height (φBF) and series resistance (Rs) obtained from I-V-T measurements were found to be strongly temperature dependent while (φBo) increase, (n), (φBF) and (Rs) decrease with increasing temperature. The apparent Richardson constant was found to be 2.1x10-9 Acm-2K-2 and mean barrier height of 0.19 eV. After barrier height inhomogeneities correction, by assuming a Gaussian distribution (GD) of the barrier heights, the Richardson constant and the mean barrier height were obtained as 23 Acm-2K-2 and 1.78eV, respectively. The corrected Richardson constant was very closer to theoretical value of 26 Acm-2K-2. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrical%20properties" title="electrical properties">electrical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=Gaussian%20distribution" title=" Gaussian distribution"> Gaussian distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=Pd-GaN%20Schottky%20diodes" title=" Pd-GaN Schottky diodes"> Pd-GaN Schottky diodes</a>, <a href="https://publications.waset.org/abstracts/search?q=thermionic%20emission" title=" thermionic emission"> thermionic emission</a> </p> <a href="https://publications.waset.org/abstracts/7401/temperature-dependent-barrier-characteristics-of-inhomogeneous-pdn-gan-schottky-barrier-diodes-surface" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7401.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">283</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2271</span> Effect of Spatially Correlated Disorder on Electronic Transport Properties of Aperiodic Superlattices (GaAs/AlxGa1-xAs)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20Bendahma">F.

In spite of the presence of disorder, the system exhibits two kinds of sets of propagating states lying below the barrier due to the characteristic structure of the superlattice. This result allows us to note the existence of a single laser emission in trimer and wavelengths are obtained in the mid-infrared. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=infrared%20%28IR%29" title="infrared (IR)">infrared (IR)</a>, <a href="https://publications.waset.org/abstracts/search?q=laser%20emission" title=" laser emission"> laser emission</a>, <a href="https://publications.waset.org/abstracts/search?q=superlattice" title=" superlattice"> superlattice</a>, <a href="https://publications.waset.org/abstracts/search?q=trimer" title=" trimer "> trimer </a> </p> <a href="https://publications.waset.org/abstracts/34254/effect-of-the-aluminum-fraction-x-on-the-laser-wavelengths-in-gaasalxga1-xas-superlattices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34254.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">455</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2269</span> Aperiodic and Asymmetric Fibonacci Quasicrystals: Next Big Future in Quantum Computation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jatindranath%20Gain">Jatindranath Gain</a>, <a href="https://publications.waset.org/abstracts/search?q=Madhumita%20DasSarkar"> Madhumita DasSarkar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sudakshina%20Kundu"> Sudakshina Kundu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Quantum information is stored in states with multiple quasiparticles, which have a topological degeneracy.

There are two types of Chebyshev polynomials, a Chebyshev polynomial of first kind and a Chebyshev polynomial of second kind. Chebyshev polynomial of second kind can be derived from the Chebyshev polynomial of first kind. Chebyshev polynomial is a polynomial of degree n and satisfies a second order homogenous differential equation. We consider the difference equations which are related with Chebyshev, Fibonacci and Lucas polynomias.

From the I–V characteristics of the Schottky diode, ideality factor (n) and barrier height (Φb) values of 1.22 and 0.56 eV, respectively, were obtained from a forward bias I–V plot. In addition, the interface states distribution profile as a function of (Ess − Ev) was extracted from the forward bias I–V measurements by taking into account the bias dependence of the effective barrier height (Φe) for the Schottky diode. The C–V curves gave a barrier height value higher than those obtained from I–V measurements. This discrepancy is due to the different nature of the I–V and C–V measurement techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Schottky%20diodes" title="Schottky diodes">Schottky diodes</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency%20dependence" title=" frequency dependence"> frequency dependence</a>, <a href="https://publications.waset.org/abstracts/search?q=barrier%20height" title=" barrier height"> barrier height</a>, <a href="https://publications.waset.org/abstracts/search?q=interface%20states" title=" interface states "> interface states </a> </p> <a href="https://publications.waset.org/abstracts/5577/characterization-of-current-voltage-i-v-and-capacitance-voltage-frequency-c-v-f-features-of-augan-schottky-diodes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5577.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">309</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2265</span> The Combination Of Aortic Dissection Detection Risk Score (ADD-RS) With D-dimer As A Diagnostic Tool To Exclude The Diagnosis Of Acute Aortic Syndrome (AAS)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Hamada%20Abdelkader%20Fayed">Mohamed Hamada Abdelkader Fayed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: To evaluate the diagnostic accuracy of (ADD-RS) with D-dimer as a screening test to exclude AAS.

Mamor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> GaN-based compounds have attracted much interest in the fabrication of high-power, high speed and high-frequency electronic devices. Other examples of GaN-based applications are blue and ultraviolet (UV) light-emitting diodes (LEDs). All these devices require high-quality ohmic and Schottky contacts. Gaining an understanding of the electrical characteristics of metal/GaN contacts is of fundamental and technological importance for developing GaN-based devices. In this work, the barrier characteristics of Pt and Pd Schottky contacts on n-type GaN were studied using temperature-dependent forward current-voltage (I-V) measurements over a wide temperature range 80–400 K. Our results show that the barrier height and ideality factor, extracted from the forward I-V characteristics based on thermionic emission (TE) model, exhibit an abnormal dependence with temperature; i.e., by increasing temperature, the barrier height increases whereas the ideality factor decreases. This abnormal behavior has been explained based on the TE model by considering the presence of double Gaussian distribution (GD) of nonhomogeneous barrier height at the metal/GaN interface. However, in the high-temperature range (160-400 K), the extracted value for the effective Richardson constant A* based on the barrier inhomogeneity (BHi) model is found in fair agreement with the theoretically predicted value of about 26.9 A.cm-2 K-2 for n-type GaN. This result indicates that in this temperature range, the conduction current transport is dominated by the thermionic emission mode. On the other hand, in the lower temperature range (80-160 K), the corresponding effective Richardson constant value according to the BHi model is lower than the theoretical value, suggesting the presence of other current transport, such as tunneling-assisted mode at lower temperatures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Schottky%20diodes" title="Schottky diodes">Schottky diodes</a>, <a href="https://publications.waset.org/abstracts/search?q=inhomogeneous%20barrier%20height" title=" inhomogeneous barrier height"> inhomogeneous barrier height</a>, <a href="https://publications.waset.org/abstracts/search?q=GaN%20semiconductors" title=" GaN semiconductors"> GaN semiconductors</a>, <a href="https://publications.waset.org/abstracts/search?q=Schottky%20barrier%20heights" title=" Schottky barrier heights"> Schottky barrier heights</a> </p> <a href="https://publications.waset.org/abstracts/179086/double-gaussian-distribution-of-nonhomogeneous-barrier-height-in-metaln-type-gan-schottky-contacts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179086.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">61</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2262</span> In Agile Projects - Arithmetic Sequence is More Effective than Fibonacci Sequence to Use for Estimating the Implementation Effort of User Stories</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Jaber">Khaled Jaber</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The estimation of effort in software development is a complex task. The traditional Waterfall approach used to develop software systems requires a lot of time to estimate the effort needed to implement user requirements. Agile manifesto, however, is currently more used in the industry than the Waterfall to develop software systems. In Agile, the user requirement is referred to as a user story. Agile teams mostly use the Fibonacci sequence 1, 2, 3, 5, 8, 11, etc. in estimating the effort needed to implement the user story. This work shows through analysis that the Arithmetic sequence, e.g., 3, 6, 9, 12, etc., is more effective than the Fibonacci sequence in estimating the user stories.

A common solution to this problem is Positional Encoding (PE), which has become quite popular. However, PE has drawbacks. It has high-frequency artifacts and adds another hyper hyperparameter, just like batch normalization and dropout do. We believe that under certain circumstances, PE is not necessary, and a smarter construction of the network architecture together with a smart training method is sufficient to achieve similar results. In this paper, we show that very simple MLPs can quite easily output a frequency when given input of the half-frequency and quarter-frequency. Using this, we design a network architecture in blocks, where the input to each block is the output of the two previous blocks along with the original input. We call this a Fibonacci Network. By training each block on the corresponding frequencies of the signal, we show that Fibonacci Networks can reconstruct arbitrarily high frequencies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neural%20networks" title="neural networks">neural networks</a>, <a href="https://publications.waset.org/abstracts/search?q=positional%20encoding" title=" positional encoding"> positional encoding</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20frequency%20intepolation" title=" high frequency intepolation"> high frequency intepolation</a>, <a href="https://publications.waset.org/abstracts/search?q=fully%20connected" title=" fully connected"> fully connected</a> </p> <a href="https://publications.waset.org/abstracts/171416/the-fibonacci-network-a-simple-alternative-for-positional-encoding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171416.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">105</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2259</span> Application of Golden Ratio in Contemporary Textile Industry and Its Effect on Consumer Preferences</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rafia%20Asghar">Rafia Asghar</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Hafeez"> Abdul Hafeez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research aims to determine the influence of Fibonacci numbers and golden ratio through textile designs.

The effect of the spin-S magnitude, as well as the effect of diversity between Landé g-factors of magnetic constituents on system entanglement, is exhaustively analyzed upon the variation of the external magnetic and electric field, respectively. It was identified that the increasing magnitude of the spin-S species in a mixed spin-(1/2,S) Heisenberg dimer with comparative Landé g-factors have always a reduction effect on a degree of the quantum entanglement, but it strikingly shifts the thermal entanglement to the higher temperatures. Surprisingly, out of the limit of identical Landé g-factors, the increasing magnitude of spin-S entities can enhance the system entanglement in both low and high magnetic fields. Besides this, we identify that the analyzed dimer with a high-enough magnitude of the spin-S entities at a sufficiently high magnetic field can exhibit unconventional thermally driven re-entrance between the entangled and unentangled mixed state.

We investigate the structural, electronic, and magnetic properties of recently experimentally synthesized (LaNiO₃)n/(CaMnO₃)m superlattices with varying LaNiO₃ thickness using density functional theory. The effect of the on-site Coulomb interaction is discussed. In switching from zero to finite U value for Ni atoms, LaNiO₃ shows transitions from half-metallic to metallic character, while spinning ordering changes from paramagnetic to ferromagnetic (FM). For CaMnO₃, U < 3 eV on Mn atoms results in G-type anti-FM spin ordering whereas increasing U value yields FM ordering. In superlattices, metal to insulator transition was achieved with a reduction of LaNiO₃ thickness. The system with one layer of LaNiO₃ yields insulating character. Increasing LaNiO₃ to two layers and above results in the onset of the metallic character with a major contribution from Ni and Mn 3d eg states. Our results for interfacial ferromagnetism, induced Ni magnetic moments and novel antiferromagnetically coupled Ni atoms are consistent with the recent experimental findings. The possible origin of the emergent magnetism is proposed in terms of the exchange interaction and Anderson localization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=density%20functional%20theory" title="density functional theory">density functional theory</a>, <a href="https://publications.waset.org/abstracts/search?q=interfacial%20magnetism" title=" interfacial magnetism"> interfacial magnetism</a>, <a href="https://publications.waset.org/abstracts/search?q=metal-insulator%20transition" title=" metal-insulator transition"> metal-insulator transition</a>, <a href="https://publications.waset.org/abstracts/search?q=Ni%20magnetism." title=" Ni magnetism."> Ni magnetism.</a> </p> <a href="https://publications.waset.org/abstracts/94575/theoretical-investigation-of-the-origin-of-interfacial-ferromagnetism-of-lanio3ncamno3m-superlattices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94575.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">237</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2253</span> Predicting the Adsorptive Capacities of Biosolid as a Barrier in Soil to Remove Industrial Contaminants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Aguedal">H.

To protect the groundwater, in this study, we proceeded to test the reliability of a bio solid as barrier to prevent the migration of a very dangerous pollutant ‘Cadmium’ through the different soil layers. The follow-up the influence of several parameters, such as: turbidity, pluviometry, initial concentration of cadmium and the nature of soil, allow us to find the most effective manner to integrate this barrier in the soil. From the results obtained, we noted the effective intervention of the barrier. Indeed, the recorded passing quantities are lowest for the highest rainfall; we noted that the barrier has a better affinity towards higher concentrations; the most retained amounts of cadmium has been in the top layer of the two types of soil, while the lowest amounts of cadmium are recorded in the inner layers of soils. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption%20of%20cadmium" title="adsorption of cadmium">adsorption of cadmium</a>, <a href="https://publications.waset.org/abstracts/search?q=barrier" title=" barrier"> barrier</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater%20pollution" title=" groundwater pollution"> groundwater pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=protection" title=" protection"> protection</a> </p> <a href="https://publications.waset.org/abstracts/32763/predicting-the-adsorptive-capacities-of-biosolid-as-a-barrier-in-soil-to-remove-industrial-contaminants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32763.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">372</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2252</span> The Nonlinear Optical Properties Analysis of AlPc-Cl Organic Compound</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Benhaliliba">M.

X-ray pattern reveals the crystalline structure along with the (242) orientation of the AlPc organic thin layer. UV-Vis shows the frequency selective behavior of the device. The absorbance of such layer exhibits a high value within the UV range and two consecutive peaks within visible range. Spin coating is used to make an organic diode based on the Aluminium-phthalocynanine (AlPc-Cl) molecule. Under dark and light conditions, electrical characterization of Ag/AlPc/Si/Au is obtained. The diode's high rectifying capability (about 1x104) is subsequently discovered. While the height barrier is constant and saturation current is greatly reliant on light, the ideality factor of such a diode increases to 6.9 which confirms the non-ideality of such a device. The Cheung-Cheung technique is employed to further the investigation and gain additional data such as series resistance and barrier height. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AlPc-Cl%20organic%20material" title="AlPc-Cl organic material">AlPc-Cl organic material</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20optic" title=" nonlinear optic"> nonlinear optic</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20filter" title=" optical filter"> optical filter</a>, <a href="https://publications.waset.org/abstracts/search?q=diode" title=" diode"> diode</a> </p> <a href="https://publications.waset.org/abstracts/148773/the-nonlinear-optical-properties-analysis-of-alpc-cl-organic-compound" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148773.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">149</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2251</span> The Structural and Electrical Properties of Cadmium Implanted Silicon Diodes at Room Temperature</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20O.%20Bodunrin">J.

Cadmium was implanted at the energy of 160 KeV to the fluence of 10¹⁵ ion/cm². The results obtained indicate that the diodes were well fabricated, and the introduction of cadmium results in a change in behavior of the diodes from normal exponential to ohmic I-V behavior. The C-V measurements, on the other hand, show that the measured capacitance increased after cadmium doping due to the injected charge carriers. The doping density of the p-Si material and the device's Schottky barrier height was extracted, and the doping density of the undoped p-Si material increased after cadmium doping while the Schottky barrier height reduced. In general, the results obtained here are similar to those obtained on the diodes fabricated on radiation-hard material, indicating that cadmium is a promising metal dopant to improve the radiation hardness of silicon. Thus, this study would assist in adding possible options to improve the radiation hardness of silicon to be used in high energy physics experiments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cadmium" title="cadmium">cadmium</a>, <a href="https://publications.waset.org/abstracts/search?q=capacitance-voltage" title=" capacitance-voltage"> capacitance-voltage</a>, <a href="https://publications.waset.org/abstracts/search?q=current-voltage" title=" current-voltage"> current-voltage</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20energy%20physics%20experiment" title=" high energy physics experiment"> high energy physics experiment</a>, <a href="https://publications.waset.org/abstracts/search?q=x-ray%20crystallography" title=" x-ray crystallography"> x-ray crystallography</a>, <a href="https://publications.waset.org/abstracts/search?q=XRD" title=" XRD"> XRD</a> </p> <a href="https://publications.waset.org/abstracts/130038/the-structural-and-electrical-properties-of-cadmium-implanted-silicon-diodes-at-room-temperature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130038.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">139</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2250</span> Effect of Epoxy-ZrP Nanocomposite Top Coating on Inorganic Barrier Layer </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Haesook%20Kim">Haesook Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Ha%20Na%20Ra"> Ha Na Ra</a>, <a href="https://publications.waset.org/abstracts/search?q=Mansu%20Kim"> Mansu Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun%20Gi%20Kim"> Hyun Gi Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung%20Soo%20Kim"> Sung Soo Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Epoxy-ZrP (α-zirconium phosphate) nanocomposites were coated on inorganic barrier layer such as sputtering and atomic layer deposition (ALD) to improve the barrier properties and protect the layer.

Large area MoS2 and WS2 nanofilms are stacked by layer transfer process to achieve thicker photo-active material studied by atomic force microscopy showing a thickness in the range of ~200 nm. Two major vibrational active modes associated with 2D-layered MoS2 and WS2 are studied by Raman spectroscopic technique to estimate the quality of the nanofilms. Schottky-barrier solar cells employed MoS2 and WS2 active materials exhibited photoconversion efficiency of 1.8 % and 1.7 % respectively. Fermi-level pinning at metal/semiconductor interface, electronic transport and possible recombination mechanisms are studied in the Schottky-barrier solar cells. <p
