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.
