Home Encyclopedia Brillouin_zoneBrillouin zoneIn mathematics and solid state physics, the first Brillouin zone is a uniquely defined primitive cell of the reciprocal lattice in the frequency domain. It is found by the same method as for the Wigner-Seitz cell in the Bravais lattice. The importance...
Since the crystalline potential is periodic, an expansion of the electron energy band can be made in terms of vectors of the direct lattice. This method is applied to GaAs and Si quantum wells and quantum wires with square and rectangular cross sections of [001] and [110] orientation, and ...

This is a more natural point of view with reference to electron beams when the smoothness assumption is not attainable, like in the lattice formulation of the Floquet–Bloch theory. Regarding the modeling of global phase factors referring to electron beams on the Brillouin zone, the most ...
