Theory of Surface Clusters in External Fields: Influence of Multipole Embedding on Local Adsorbate Binding

  • K. Hermann
Part of the NATO ASI Series book series (NSSB, volume 283)


From a theoretical point of view an adsorbate system represents a very complex quantum mechanical many-particle system which requires a fair number of severe approximations to allow a theoretical treatment[1,2]. The interaction of the adsorbate, atom or molecule, with the substrate surface is determined by local contributions such as chemical binding or local ionici-ties which involve substrate atoms close to the adsorption site. Further, there are environmental contributions which reflect the fact the adsorption site atoms are coupled electronically to the rest of the substrate.
