Calculation of phonons on the Cu(100) surface by the embedded-atom method

Calculations, based on the embedded-atom method of phonon energies and polarizations on the clean Cu(100) surface, are presented. The atomic relaxations and the dynamical matrix are obtained, without fitting to surface properties, in one consistent calculation which is no more computationally demand...
