Diffusion and Interaction of Adatoms

  • G. Ehrlich
Part of the Springer Series in Surface Sciences book series (SSSUR, volume 2)


Compared to the wealth of information now available about atomic arrangements in overlayers and surfaces, rather little is known about the energetics governing the atomic interactions which underlie the structures formed. This imbalance has been redressed somewhat, as recently considerable information has been derived about atomic interactions from Monte Carlo simulations [60.1–3]. In these studies, interactions between atoms in a lattice gas are varied until the simulations match the experimentally observed phase diagram for the adsorbed layer. This macroscopic and rather indirect approach has also been complemented by insights concerning interactions at surfaces derived by direct examination on the atomic level.
