摘　　要：CdZnTe材料具有较宽的禁带宽度和化学稳定性,使其成为制备紫外光电探测器的理想材料.电极与CdZnTe材料之间良好的接触特性对制备高灵敏度和高稳定性的紫外探测器具有关键作用.制备了单电极Au/CdZnTe/Au探测器和复合电极Au/GaZnO(GZO)/CdZnTe/GZO/Au探测器,研究了不同电极对CdZnTe紫外光电探测器性能的影响.CdZnTe has a wide band gap and chemical stability,making it an ideal material for the preparation of UV(ultraviolet)photodetectors.Good contact between the electrode and CdZnTe plays a key role in the preparation of highly sensitive and stable UV detec-tors.In this work,a single electrode Au/CdZnTe/Au detector and a composite electrode Au/GaZnO(GZO)/CdZnTe/GZO/Au detector were prepared,and the effects of different electrodes on the performance of CdZnTe UV photodetectors were investigated.
