Simulating Surfaces by the Summation of Pairwise Interatomic Potentials
Workers in surface science are often led, for lack of other more precise methods, to simulate surfaces by the computer summation of pairwise interatomic potentials, usually of very simple forms. In this paper, this approach is considered for a variety of surface problems. The surface collision problems: atom surface scattering and surface atom ejection are discussed in detail, and a new simulation of the latter is reported. The planar relaxation of surface layers is considered as a possible source of information on surface potentials.
