Phys. Rev. B 66, 045208 (2002) [15 pages]Atomistic description of the electronic structure of InxGa1-xAs alloys and InAs/GaAs superlatticesReceived 12 March 2002; published 30 July 2002 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. © 2002 The American Physical Society URL:
