LETTER TO THE EDITOR

The electronic structure at the interface between bulk GaAs(001) and short-period superlattices of (AlAs)n(GaAs)m has been calculated using ab initio pseudopotential techniques. The results show that the valence band offsets at such interfaces are very similar to those obtained experimentally for random alloy systems, but superior transport properties are anticipated for the ordered systems.
