Paper Abstract

In the paper, the problem of the effective enhancement of electron capture efficiency has been considered for MQW structures. Different approaches to the problem are used. The most effective one is based on embedding of additional layers in SQH region. We have investigated the influence of such layers on two types of carriers' capture. The first one is the capture of bound carriers from reservoir states in SQH region and the second one is the capture of free carriers from quasi-continuum states. As a result, we have obtained up to tenfold increase of electron capture efficiency.
