Abstract
In this paper we calculate the surface thermal expansion of Ag(1 1 0). applying the perturbation theory to treat the effects of the anharmonic part of the interatomic potential. Results relative to the relaxation of the interlayer distance are presented for different temperatures. These results confirm the alternate contraction and expansion at room temperature and the enhancement of the anharmonicity in the surface region. (C) 2002 Elsevier Science B.V.
