INTERPLAY OF MELTING, WETTING, OVERHEATING AND FACETING ON METAL-SURFACES - THEORY AND SIMULATION

In this work attention is focussed on the behavior of metal surfaces, in particular on the phenomena observed at high temperature, i.e. near and above the melting point of the given material. Some new ideas are presented on the interrelation of phenomena which are commonly treate d separately. In particular an attempt is made to clarify relations wh ich exist among phenomena like melting/non-melting, wetting overheatin g, layering and faceting of surfaces, and their interplay in determini ng the crystal shape, or the physical state of the surface, at high T.
