Title: Ultrathin film of nickel on the Cu (100) surface: Atomic structure and phonons

We investigated the structural and vibrational properties of the Cu (100) surface covered with ultrathin (1-5 ML) Ni films using interaction potential from the embedded atom method. The surface relaxation, dispersion relation and polarization of vibrational modes are discussed. Our calculated structural parameters are in good agreement with experimental results. The obtained vibrational frequencies compare well with the available experimental data.
