Abstract

The adsorption energies and stable configurations of adlayers on different substrates of various orientations are calculated by means of a pairwise interaction model based on Lennard-Jones potentials. The adlayer is adsorbed onto a substrate consisting of a variable number of relaxed surface layers surmounting a much larger number of “rigid” layers fixed at bulk spacing. Special consideration is given to the adsorption of Cu, Ag and Pb on W and the adsorption of Ag on Cu.
