Solute-vacancy binding energies in noble-metal-based dilute alloys

Abstract

Abstract The phase shifts determined from a fit to the Fermi surface and Dingle tempera-ture data have been used to calculate the solute–vacancy binding energies of several solutes in noble metals. The usual asymptotic form of the induced electron density has been employed. Since the phase shifts of noble metals are quite significant, especially in comparison to those of the solutes studied in the present work, the effect of the generally ignored host phase shifts on the induced electron density and the binding energy has been investigated. It is found that the binding energies are substantially affected by the inclusion of the host phase shifts.
