对于InGaZnO材料作为沟道半导体的薄膜晶体管柔性显示器件的研究倍受关注。将Ga2O3,In2O3,ZnO高纯度粉末按一定比例混合,经过研磨、预烧、研磨、压模和烧结,利用常压固相反应烧结法制备了直径为30 mm,厚度为5 mm高质量的InGaZnO陶瓷靶材,并对InGaZnO靶材进行了X射线衍射(XRD)测试。采用脉冲激光沉积的方法,一定温度下在石英玻璃衬底上生长了InGaZnO薄膜,并对薄膜进行原子力显微镜、透射光谱与霍尔效应的测试与表征,制备出具有高平整度、高透射率与优异电学性质的透明氧化物半导体(TOS)薄膜,为进一步对InGaZnO薄膜的制备与分析提供良好的实验数据支持。

设计了一种非对称臂马赫-曾德尔干涉仪(MZI)型硅基二氧化硅偏振分束器(PBS), 在1535~1565 nm波长范围内, 其偏振消光比大于20 dB, 插入损耗大于-0.5 dB。采用有限差分-束传播法(FD-BPM)进行误差分析, 分别计算了多模波导的宽度和长度以及非对称臂的宽度和长度误差对偏振分束器性能的影响。仿真结果表明, 多模波导长度和非对称臂长度误差分别小于±2 μm和±4 μm时, 偏振分束器的消光比和插入损耗仍能保持较好的结果; 而要保持20 dB以上的偏振消光比, 多模波导宽度误差应小于
