Abstract

The Lennard-Jones 6:12 atom interaction potential is applied to the calculation of adsorption energy of an atom onto a network of sites on a unit cell surface area for each of the eight highest surface density planes of a face-centered-cubic substrate. From the calculations, a normalized adsorption energy is plotted as a function of position on each plane for various adsorbate-adsorbent conbinations. Normalized values of maximum adsorption energies and minimum surface diffusion activation energies are tabulated.
