Abstract
Computer simulation and lattice dynamics have been used to investigate phonons propagating in monolayers, bilayers, and trilayers of xenon physisorbed on a Ag(111) surface. Agreement with the experimentally determined dispersion of the surface phonons has been achieved by the use of a realistic interatomic potential for the Xe adatoms and a new surface-adatom potential.Keywords
