In solids one could find place where the atom should be, but missing. Such places are called vacancies. With increasing of temperature neighbor atom could jump on the vacancy, so vacancy will disappear in place where it was, but appear in the place, where atom was. This process is stochastic, so vacancy will move in random direction. Density of vacancies will change in time with accordance to diffusion equation.

What else can I help you with?
