Empty lattice approximation

The empty lattice approximation is a theoretical electronic band structure model in which the potential is periodic and weak (close to constant). One may also consider an empty[clarification needed] irregular lattice, in which the potential is not even periodic. The empty lattice approximation describes a number of properties of energy dispersion…
