Potential Energies of a Silver Atom Adsorbed on Flat and Stepped Surfaces of Sodium Chloride Crystal

Abstract: The potential energies of an isolated silver adatom on NaCl crystal surface is calculated by using dispersion, electrostatic, and repulsive potentials. They have a minimum value (-0.62 eV) above each sodium ion site in the flat (001) surface and a pair of minimum values (-1.10 eV) in the vicinity of each sodium ion site on the lower terrace along a step in the stepped (1 0 11) surface. From the results, the surface diffusion of an adatom on the flat and stepped surfaces is discussed in comparison with experime… Show more
