Abstract
We show how an empirical pseudopotential approach, fitted to bulk and interfacial reference systems, provides a unified description of the electronic structure of random alloys (bulk and epitaxial), superlattices, and related complex systems. We predict the composition and superlattice-period dependence of the band offsets and interband transitions of InAs/GaAs systems on InP and GaAs substrates.
