    • The Cu-metal surface clean and covered with Cu adatoms was modeled by a two-dimensional periodic slab consisting of 31 atomic layers of Cu(111) with supercells (6×6 ), large enough to exclude direct interactions between neighboring cells. The chosen thickness prevents also the interactions between the two opposite surfaces of the film. The Cu single adatoms and triangle clusters were arranged in a corresponding adsorption structure above both terminations of the slab. The calculations of vibrational spectra were carried out by the dynamical matrix method. Diagonalizing the matrix gives the frequencies and polarization vectors of vibrations. The local vibration densities of states were obtained by projecting these eigenmodes onto atoms of interest in a given ( x+y or z) direction.
