Abstract

The long standing problem of determining band offsets at semiconductor interfaces is readdressed. We show that the valence‐band discontinuity can be extracted from a knowledge of the local density of states across the interface. This method can also be used to determine the band offsets in superlattice structures. The concept of band offsets in short period superlattices is examined. It is shown that this is intimately connected with the localization of bands in one or other of the superlattice constituents
