The general vibrational properties of epitaxially grown fcc Cu films on Ni(001) have been studied using a central-force lattice-dynamical slab model. The theoretical results predicted the emergence of new film modes as the overlayer film's thickness increases. Calculated phonon dispersion curves and spectral densities are presented and the regions of different localizations for the phonon modes in the two-dimensional projected phonon band have been identified.
