Several points of high symmetry are of special interest – these are called critical points. [3] Other lattices have different types of high-symmetry points. They can be found in the illustrations below. See also [ edit] Brillouin-zone construction by selected area diffraction, using 300 keV electrons. Fundamental … See more In mathematics and solid state physics, the first Brillouin zone is a uniquely defined primitive cell in reciprocal space. In the same way the Bravais lattice is divided up into Wigner–Seitz cells in the real lattice, the See more • Kittel, Charles (1996). Introduction to Solid State Physics. New York: Wiley.
