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.
