Abstract
The collision induced migration (CIM) of adsorbates on surfaces is identified and discussed. The CIM process has been studied using molecular dynamics simulations of the Ar/N2/Ru(001) system. The single adsorbed molecule can migrate over 150 angstroms following collisions at high energies and large angles of incidence. As coverage increases, inter-adsorbate collisions efficiently quench the migration distance. At high energies, the competing collision induced desorption becomes dominant, leaving behind only low energy adsorbates which migrate to relatively short distances.
