Abstract

When the temperature of a crystal approaches the bulk melting point T M , some low-index surfaces begin to pre-melt below T M (surface melting), and some do not (surface non-melting). In surface melting, a ‘quasi-liquid’ layer forms at the crystal-vapour interface. Its thickness diverges characteristically as some power of 1 /(T M T), as T M T tends to zero. In surface non-melting, conversely, the quasi-liquid layer does not form at all, or else it may begin to form, but then its growth is ‘blocked’ to some small thickness, which, does not diverge.
