Abstract
An efficient self-consistent Green's-function technique using a genera lization of the coherent-potential approximation method is presented i n order to describe the electronic structure of inhomogeneous semi-inf inite alloys with varying concentration profiles at the surface within the local-density approximation. The formalism is applied to the stud y of the electronic properties of the (001) surface of Cu1-xNix fcc ra ndom alloys.
