Thermal vibrations at copper surfaces studied by low energy ion scattering
The thermal vibrations of surface atoms on Cu(110) have been studied as a function of temperature with impact collision ion scattering spectroscopy. Monte Carlo simulations of the scattering along chains of surface atoms show that for large vibration amplitudes more than two atoms have to be included to explain the experimental data. The mean square displacement obtained from the comparison between experiment and calculations agrees well with the results of atom scattering and inverse photoemission experiments and the results from surface phonon calculations. The influence of correlations and anisotropy of the surface vibrations on impact collision ion scattering spectra is discussed.
