MODELING CU, AG AND AU SURFACES USING EMPIRICAL POTENTIALS

Empirical potential energy functions, comprising two-and three-body te rms, have been derived for copper, silver and gold. These potentials r eproduce the experimental energies and relaxations of the (111), (110) and (100) surfaces of the fee solid, to a high degree of accuracy, an d correctly predict the 1 x 2 reconstruction of the (110) surface of g old.
