Abstract
Binding energies of metal clusters confined to two dimensions along di fferent crystallographic directions have been calculated using self-co nsistent ab initio molecular-orbital theory. The results reveal a nonm onotonic dependence of the energies on the cluster size, with conspicu ous maxima corresponding to close atomic packing. This behavior persis ts even when the interaction with a substrate is included.
