Surfaces, Interfaces, and Changing shapes in Multilayered Films

摘要

It is generally recognized that the cap- illary forces associated with internal and external interfaces affect both the shapes of liquid-vapor surfaces and wetting of a solid by a liquid. It is less commonly un- derstood that the same phenomenology often applies equally well to solid-solid or solid-vapor interfaces. The fundamental quantity governing Capillary phenomena s the excess free Energy associated with a unit area of in- Terface.
