Green's-function method for energy bands in disordered alloys. II. band structure of disordered Cu₃Au

Abstract

A generalization of the Green's-function method (proposed by the authors in a previous paper) has been used to determine the energy bands of disordered Cu₃Au. Energies have been calculated at the symmetry points Γ, X, and L for a series of temperatures above the transition temperature. The crystal potentials and the structure constants are calculated using the short-range-order parameters from the available x-ray data. The results are discussed in terms of the available experimental information for this alloy.
