We present an analysis of the vibrational dynamics of metal vicinal surfaces using the embedded atom method to describe the interaction potential and both a real space Green's function method and a slab method to calculate the phonons. We report two main general characteristics: a global shift of the surface vibrational density of states resulting from a softening of the force field. The latter is...
We present results for the temperature variation of diffusion coefficients for adatoms and vacancies on Ag(100), Cu(100), and Ni(100), using transition state theory and many-body interaction potentials from the embedded atom method. The contribution of lattice vibrations is found to be essential for the evaluation of the diffusion pre-exponential factors and is incorporated through the thermodynamic...
