Abstract
The surface lattice dynamical matrix has been derived from a new model within the framework of the Embedded Atom Method (EAM), which is based on results from density functional theory. The surface-phonon dispersions on Cu (100) in the direction Γ X was calculated. The obtained dispersion curve of the Rayleigh phonon on Cu (100) is in good agreement with experimental data by electron-energy-loss-spectroscopy (EELS).
