SURFACE ELECTRONIC-STRUCTURE AND REACTIVITY OF TRANSITION AND NOBLE-METALS

We present self-consistent density functional calculations using the L MTO-ASA method of the variations in the surface electronic structure f or pseudomorfic overlayers and impurities of Fe, Co, Ni, Cu, Ru, Ph, P d, Ag, Lr, Pt, and Au on the other metals. Knowledge of these variatio ns is of importance in understanding trends in the reactivity of metal surfaces. A simple model is presented which gives a description of th e overall trends in the self-consistently calculated results.
