Abstract

It is found that one-electron states in thin semiconductor quantum rings based on semiconductor heterostructures satisfy special selection rules associated with the presence of two nonequivalent heteroboundaries. It is shown that the existence of a single stable one-electron level in the ring with preliminarily chosen characteristics (for a given heterostructure) can be achieved by selecting outer and inner ring radii.

半导体量子环中一电子态的存在条件

摘要

发现基于半导体异质结构的薄半导体量子环中的单电子态满足与两个非等价异界的存在相关的特殊选择规则。结果表明，通过选择外环半径和内环半径，可以在具有预先选择的特性（对于给定的异质结构）的环中存在单个稳定的单电子能级。
