The Interaction of an Atom with a Surface: A Model Based on Effective Medium Theory

  • M. Karimi (a1) and G. Vidali (a2)

Abstract

The interaction potential between an atom and a surface is constructed using the “effective medium theory” (EMT) for the repulsive part of the interaction, and the damped dipole-dipole and dipole-quadrupole Van der Waals terms for the attractive part. This model is then applied to the following systems: He/MgO, LiF, NaCl, Ag and Cu.
