THE EQUILIBRIUM OF CRYSTAL SURFACES.

Abstract

The purpose of this paper is to review the basic principles underlying the theory of crystal surfaces, giving particular attention to the phenomenological thermodynamic point of view. The basic equation for the equilibrium of crystal surfaces is discussed from a general viewpoint. It will be emphasized that there are two main differences with respect to the situation in the case of fluid surfaces: a) The surface energy is anisotropic in a crystal and isotropic in a fluid b) In crystals the existence of surface stresses and connected volume stress must be taken in account. Macroscopic equilibrium will be considered. In it will be discussed the two main classical problems, faceting and equilibrium shape of small crystals. Microscopic equilibrium is also considered.
