The advantage of selecting Ardunio is, it has pulse width modulation (PWM) based pins. Depending on the width of the pulse, the output voltage changes which will intern changes the speed of the DC motor connected to the PWM pin. The thickness of deposited film using spin coater depends on RPM and duration of rotation. The rotation of the substrate during deposition has three stages a gradual increase in RPM, maintaining constant RPM over a while, and a gradual decrease in RPM. All these parameters can be controlled by an Arduino board. An Aluminum doped Zinc Oxide film was deposited on glass substrate using Arduino based spin coater. X-ray diffraction, UV – VIS spectroscopy, and FTIR methods were used as characterization techniques. Hexagonal crystal structure of deposited AZO layer was confirmed by XRD and optical band gap, transparency were calculated by UV-VIS spectroscopy. </div> <div> <a data-readmore="{ block: '#abstractTextBlock578770', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 49 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMR.651.60">Preparation of AZO Thin Films by Level Sedimentation and its Optical and Electrical Properties</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: De Wen Gao, Tian Lan Yin, Guang Ming Wu, Guang Jian Xing, Yao Ding, Yang Zhou </div> </div> <div id="abstractTextBlock262148" class="volume-info volume-info-text volume-info-description"> Abstract: AZO precursor solution was prepared with dihydrate zinc acetate as raw materials, ethylene glycol monomethyl ether and ethanol as solvent, ethanolamine as a stabilizer, hexahydrate aluminum chloride as the dopant. The AZO thin films were prepared on glass substrates by using homemade liquid level settlement device. The orthogonal design of the experimental conditions was made to optimize the conditions of this method for the preparation of AZO thin films. The films were analyzed by XRD, UV-Vis, AFM, four-probe, step profiler and other methods. The results show that the optimal conditions for preparation of AZO thin films were as follows: the sol concentration was 0.5mol/L, the Al<sup>3+</sup>/Zn<sup>2+</sup> concentration ratio was 4 at%, the drying temperature was 100 °C for 10 minutes, the pretreatment temperature was 450 °C, the coating layers were 20, the level settling velocity was 5 cm/min, the pretreatment time was 10 minutes, the annealing temperature was 550 °C for 2 h. The average transmittance in visible light and the sheet resistance of the AZO thin films were 88% and 536Ω/□, respectively. </div> <div> <a data-readmore="{ block: '#abstractTextBlock262148', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 60 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMM.117-119.1076">Thickness Dependence of Structural and Optical Characteristics of AZO Thin Films for Organic Photovoltaic Cells</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: S.L.

The effect of thickness on structural and optical characteristics of the deposited films were investigated by X-ray diffractometer and spectrophotometer. The results show that the polycrystalline AZO films consist of the hexagonal crystal structures with c-axis as the preferred growth orientation normal to the substrate, and that the thickness significantly affects the crystal structure and optical properties of the thin films. With the increase of thickness, the crystallite size of the films increases, the lattice spacing, dislocation density, micro strain and optical energy gap decrease, and the average transmitance in the wavelength range of the visible spectrum also slightly decreases. </div> <div> <a data-readmore="{ block: '#abstractTextBlock143424', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 1076 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMR.306-307.1402">The Electrical and Optical Properties of Al-Doped ZnO Thin Films Prepared by Atomic Layer Deposition</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Jia Song, Hai Chuan Mu, Lai Xing Jiang, Gui Lin Yin, Zhen Yu, Dan Nong He </div> </div> <div id="abstractTextBlock125180" class="volume-info volume-info-text volume-info-description"> Abstract: Al-doped ZnO (AZO) thin films (~100nm) with low electrical resistivity and high transparency have been prepared by atomic layer deposition on glass and Si(111) substrates at 200 °C with different doping sequence. The films were systematically analyzed using X-ray diffraction, scanning electron microscope (SEM), UV-vis spectroscopy and Hall measurement. XRD patterns showed that all the films were well crystallized with hexagonal wurtzite structure with preferred orientation along (100) plane. The resisitivity of films deposited with doping sequence of DEZ/TMA/H<sub>2</sub>O was lower than that with other doping sequences. Results from SEM showed a worm-like shape and similar grain sizes of AZO films.

Aluminum doped zinc oxide has become one of the most promising transparent conductive oxide (TCO) materials because of its excellent optical and electrical properties. In this work, aluminum doped zinc oxide thin films were prepared using RF magnetron sputtering of a 4 at% ceramic target. The thermal stability of aluminum doped zinc oxide thin films was studied using various physical and structural characterization methods. It was observed that the electrical conductivity of aluminum doped zinc oxide thin films deteriorated rapidly and unevenly when it was heated up to 350 °C. When the aluminum doped zinc oxide thin films were exposed to UV ozone for a short time before heating up, its thermal stability and large area homogeneity were significantly improved. The present work provided a novel method for improving the durability of aluminum doped zinc oxides as transparent conductive electrodes in thin film solar cells. </div> <div> <a data-readmore="{ block: '#abstractTextBlock121648', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 147 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMR.239-242.1626">Influence of Substrate Temperature on the Properties of Al-Doped Zinc Oxide Films Prepared by DC Reactive Magnetron Sputtering</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Chang Hu Yang, Zhong Quan Ma </div> </div> <div id="abstractTextBlock108685" class="volume-info volume-info-text volume-info-description"> Abstract: Transparent and conductive c-axis oriented aluminum-doped zinc oxide (AZO) films have been prepared on glass substrate by dc reactive magnetron sputtering process.

As the substrate temperature increased, the results showed that grain size of the AZO films gradually increased, the films had a strong c-axis oriented and the crystallization of films became better. The absorption edge first shows a red shift, and then switches to the blue shift with increasing substrate temperature. Optical band gap of AZO films first decreases and then increases with increasing substrate temperature. Resistivity of AZO films decreases with increasing substrate temperature but the rate of decline of resistivity becomes slow after substrate temperature reaches 250 °C. The carriers concentration of AZO films increases with substrate temperature increase. </div> <div> <a data-readmore="{ block: '#abstractTextBlock108685', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 1626 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMR.194-196.2334">Stability of AZO Thin Films under the Environment of Hydrogen Plasma</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Qing Nan Zhao, Wen Hui Yuan, Hong Yu Liang, Wei Yuan Wang, Pu Lei Yang, Yu Hong Dong </div> </div> <div id="abstractTextBlock100775" class="volume-info volume-info-text volume-info-description"> Abstract: The textured thin films of Aluminum-doped zinc oxide (AZO), prepared on glass substrates by magnetron sputtering, were treated under the environment of hydrogen plasma in plasma enhanced chemical vapor deposition (PECVD) chamber for different time.

XRD shows that all AZO films have a hexagonal wurtzite structure with prominent (002) orientation. With the plasma power increasing, the grain size first increases and then decreases. The largest grain size of 23.6 nm in the films is obtained at the plasma power of 123 W. The average optical transmittance of AZO films is over 80% in the visible region.
