Abstract

The paper presents calculation of current–voltage characteristics of Me-i-Me HR-GaAs:Cr structures compared with the experimental data. With respect to the voltage redistribution to an extremely high resistance of the i-layer, the current flow is limited by processes in the space charge region of the reverse-biased Schottky barrier formed at the i-Me interface.

基于HR-GaAs:Cr的电离辐射传感器的电流-电压特性
本文计算了Me-i-Me HR-GaAs:Cr结构的电流-电压特性,并与实验数据进行了比较。对于电压重分布到极高电阻的i层,电流流动受到在i-Me界面形成的逆偏肖特基势垒的空间电荷区过程的限制。
