On thed-electron surface density of states of transition metals

  • Published:
Zeitschrift für Physik B Condensed Matter

Abstract

Using the moment method and the continued fraction expansion for the one-particle Green's function we have studied thed-electron surface density of states for a transition metal. Besides the reduction of nearest neighbours for a surface atom compared to a bulk atom we have also taken into account the effect that the atomic environment of a surface atom is quite different from that of a bulk atom. This leads to important modifications in the surface density of states which can effect e.g. magnetic surface properties.
