Polytype superlattices and multi-heterojunctions

Abstract

We discuss the significant implications of polytype superlattices and multi-heterostructures consisting of combinations of three semiconductors: AlSb, GaSb and InAs, which are compatible for heteroepitaxy. The triple-constituent multilayer heterostructures appear to offer not only a novel class of materials for scientific investigations but also a new breed of semiconductor devices for high-speed applications. © 1981 The Japan Society of Applied Physics.
