Abstract

A series of heterostructures consisting of a ZnTe matrix containing two CdTe monolayers separated by barrier layers of different thicknesses is studied. The dependences of the energies of the exciton radiation bands associated with narrow-band CdTe layers, their relative intensities, and temperature behavior on the thickness of the ZnTe barrier layer are determined. It is established that at a barrier layer thickness of more than 30 monolayers CdTe monolayers can be considered independent of each other.

ZnTe 基体中双 CdTe 单层的激子发光

摘要

研究了一系列由 ZnTe 基体组成的异质结构，该基体包含两个由不同厚度的阻挡层隔开的 CdTe 单层。确定了与窄带 CdTe 层相关的激子辐射带的能量、它们的相对强度和温度行为对 ZnTe 势垒层厚度的依赖性。已经确定，在超过 30 个单层的阻挡层厚度下，CdTe 单层可以被认为是彼此独立的。
