Abstract
The surface instabilities of copper metal are studied by computing the quasiharmonic free energy of (100), (110), and (111) surfaces within the slab model. We find that a loose-packed surface would melt prior to a close-packed one if contractive surface relaxations are neglected. The inclusion of surface contractions can reverse the order of these instabilities in agreement with recent experiments.Keywords
