Abstract
An efficient self-consistent Green’s-function technique using a generalization of the coherent-potential approximation method is presented in order to describe the electronic structure of inhomogeneous semi-infinite alloys with varying concentration profiles at the surface within the local-density approximation. The formalism is applied to the study of the electronic properties of the (001) surface of fcc random alloys.
