Interband Effects in the Coherent Potential Approximation: Simple Two Band Model
The CPA is applied to a two band separable pseudopotential model for a hot binary liquid alloy. The variation of the band gap with concentration is strictly linear, but the band broadening is found to be asymmetric about C = 50% and to depend in a complicated way on interband interaction.
