Abstract
- An efficient self-consistent Green's function technique to calculate electronic properties of surfaces of disordered alloys within the local density approximation is presented. The tight-binding version of the linear muffin-tin orbital method is used to describe the electronic states, while the semi-infinite nature of the system is incorporated via the surface Green's function approach. A generalization of the coherent potential approximation method in order to treat inhomogeneous systems is used to study the effect of disorder. The formalism is applied to the study of electronic properties of random CuPd overlayers of the fcc-Cu(001) substrate and of the (001) faces of fcc-CuNi random alloys.
