First principles theory of Fermi-surface driven concentration waves in Cu/sub c/Pd/sub 1-c/ alloys

Conference ·
OSTI ID:6217007
The first-principles methods are based on the use of the Korringa-Kohn-Rostoker coherent-potential approximation (KKR-CPA). A mean-field theory of ordering in alloys has been developed that is based on the KKR-CPA method for treating the underlying electronic structure. Contour maps are presented for the short-range order diffuse scattering from Cu/sub c/Pd/sub 1-c/ alloys. The expression for ..cap alpha..(K) is dominated by a contribution from the Fermi energy. The concentration waves are Fermi-surface driven. (DLC)
