摘要:
Since low energy ion scattering involves collision sequences with neighbouring atoms, it is sensitive to the surface properties. The present work emphasizes the relation between ion scattering and surface dynamics on an atomic scale. A hot surface is simulated by isothermal classical dynamics with a N-body potential known to reproduce the bulk elastic properties of copper at 0 K, as well as the full bulk phonon dispersion relations within the experimental error.
