An interface is the region that separates two bulk phases. An interface is a molecular
structure, given that one of its characteristic lengths is of molecular size. The cost
in Helmholtz energy to create such a structure is known as the the surface tension.
The simplest, most studied, and perhaps most important interface is the
fluid/fluid interface: the liquid/vapour interface of a one-component system.
Interfaces are subject to thermal noise, which leads to thermal capillary waves. See also diffusion at interfaces.
