Microscopical Theory of the Bimetallic-Interface Thermodynamic Properties. 2. A Model Calculation of the Liquid-Metals Interface Tension

摘要

On the basis of the sealing transformation method and perturbation expansion in the electron-ion pseudopotential up to the second order, an expression for the interface tension between two liquid metals is obtained. The second order contributions into the interface tension are expressed in terms of the response functions of inhomogeneous electron gas and ion distribution functions. The model calculations are made for the miscible and immiscible liquid metals.
