Abstract

Softening of the surface lattice vibration and surface lattice relaxation are discussed on the basis of a self-consistent Einstein model, laying emphasis on the anharmonic effect. One-dimensional model is considered for the illustrative purpose. It is shown that the anharmonic effect is much more enhanced on and near the surface than in the interior.
