摘要

摘要：研究首次表明，基于高电阻率光敏碲化镉层的光检测元件的输出电压、位置灵敏度和光谱灵敏度随层厚度的增加（6-60 μm）呈双曲线下降，并随输入电流的增加呈线性上升。这项研究发现的高位置灵敏度和光谱灵敏度（分别为 70.8 mV/(mm μA mW) 和 375 mV/(μA mW)）大大超过了碲化镉层，这表明高电阻率硒化镉层作为位置灵敏光电探测器的材料具有相当大的潜力。

Optical Probing Position Sensitivity Characteristics of a Photodetecting Element Based on High-Resistivity CdSe Layers

The output voltage, position sensitivity, and spectral sensitivity of a photodetecting element based on high-resistivity photosensitive CdSe layers have been shown for the first time to decrease hyperbolically with increasing layer thickness (in the range 6–60 μm) and increase linearly with increasing input electric current. The high position and spectral sensitivity found in this study (70.8 mV/(mm μA mW) and 375 mV/(μA mW), respectively), which considerably exceeds that of cadmium telluride layers, demonstrate that high-resistivity CdSe layers have considerable potential as a material of position-sensitive photodetectors.
