Electronic structure of disordered alloys—Generalized coherent-potential approximation and effects of environment

Abstract

The renormalized propagator formalism of Niizeki is used to calculate local-environment effects on the density of states of disordered alloys. Random transfer integrals of Shiba's type are included in the theory. Numerical results of density of states of a simple cubic binary alloy $A_x{B}_{1-x}$ are presented.
