## Primitive cellIn geometry, solid state physics and mineralogy, particularly in describing crystal structure, a ## Additional recommended knowledgeThe primitive cell is a fundamental domain with respect to translational symmetry only. In the case of additional symmetries a fundamental domain is smaller. A crystal can be categorized by its lattice and the atoms that lie in a primitive cell (the
u_{1}, u_{2}, and u_{3}.
The primitive cell is defined by the primitive axes (vectors) , , and . The volume, - .
A Wigner-Seitz cell is an example of another kind of primitive cell. In certain circumstances, The general mathematical concept behind the primitive cell is termed the fundamental domain or the Voronoi cell. The primitive cell of the reciprocal lattice in momentum space is called the Brillouin zone. Categories: Condensed matter physics | Crystallography | Mineralogy |
