| heal.abstract | We present molecular dynamics simulation results concerning diffusion processes happening on and near the Cu(110) surface. We found that, in our simulations, Arrhenius-type interlayer diffusion between the atomic layers near the surface becomes important above a temperature T-s = 850 K, contributing significantly to the production of adatoms, most of which combine to form dimers or trimers. These diffusion processes follow the Meyer-Neldel rule with an activation energy of 0.11 eV, indicating that their driving force comes from multiple excitations. All of these phenomena act as precursors of the high diffusivity this surface exhibits at much higher temperatures. (C) 2000 Elsevier Science B.V. All rights reserved. | en |
