A microscopic model for the liquid metal-ionic solution interface

Abstract

A microscopic model for the metal-solution interface is presented, which, for the first time, includes both a non-ideal treatment of the metal and a molecular model for the solution side. The metal is described by a jellium model including electron-ion pseudo-potential. The solution is treated as a mixture of hard spheres with point dipoles (solvent molecules) or point charges (ions). The statistical mechanics is solved using mean spherical approximation. No a priori separation is introduced between compact and diffuse layers. A simplified version of the model is applied to the case of Hg-DMSO systems.
