Abstract

The results of a study of the excitation kinetics of photoconductivity of pyrolytic CdZnS films with a nanostructured surface are presented in this paper. It is observed that the time dependences of the photoconductivity of the studied structures under their own excitation have a flash character. To explain the flash character of the time dependences of photoconductivity excitation, the model is proposed that takes into account the localization centers whose cross-section of charge carrier capture is functionally related to the optical modulation of the surface potential barrier.

纳米簇Cd 1-x Zn x S薄膜的势垒光电导性增加了光电流的非单调性

摘要

本文介绍了具有纳米结构表面的热解CdZnS薄膜的光电导激发动力学的研究结果。观察到，在其自身的激发下，所研究结构的光电导率的时间依赖性具有闪光特性。为了解释光电导激发的时间依赖性的闪烁特性，提出了考虑定位中心的模型，该定位中心的载流子俘获截面与表面势垒的光学调制在功能上相关。
