摘要：

An approach to the electronic properties of surfaces of disordered metals is developed that combines the tight-binding linear-muffin-tin-orbital method with the surface Green's-function formalism and the coherent-potential approximation. The actual composition in the top surface layers can differ from that in the bulk layers. The method is applied to evaluate component- and layer-projected densities of states for the Ag50Pd50(001) surface, assuming both uniform and nonuniform concentration profiles in the sample surface.
