High-symmetry points
Did you know?
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.
