Abstract

The spectral response and quantum efficiency of the visible-range photodetectors based on ZnSe and ZnCdSe/ZnSe heterostructures are experimentally studied. The spectral response of the detectors is characterized under various bias conditions. A model of a decrease in the effective height of a reverse-biased Schottky contact under irradiation is used to interpret the internal amplification of the detectors.

用于可见光谱范围的 ZnSe 和 ZnCdSe/ZnSe 光电探测器：比较参数

摘要

实验研究了基于ZnSe和ZnCdSe/ZnSe异质结构的可见光光电探测器的光谱响应和量子效率。检测器的光谱响应在各种偏置条件下进行表征。反向偏置肖特基接触在辐照下的有效高度减小的模型用于解释探测器的内部放大。
