Abstract

By using an empirical tight-binding method we have studied the effects of superlattice period and alloy composition on the ordering of the lowest conduction-band and valence-band states in (GaAs)n/AlxGa1-xAs)n SLs grown in the [001] and [111] directions. The calculated results of band structure are compared and discussed with the existing photoluminescence (PL) data of Hayakawa et al.
