Abstract
Vibrational modes on the Cu(100) and Cu(111) surfaces covered with a Ni mon olayer have been calculated using the embedded-atom method. A detailed disc ussion of the dispersion relations and polarizations of adsorbate modes and surface phonons is presented. The dispersion of the Rayleigh phonon is in good agreement with the experimental EELS data. The changes in interatomic force constants are discussed. (C) 1999 Published by Elsevier Science B.V.
