What is Brillouin zone? What is its physical meaning?

The electronic state of the crystal is described by wave vector k, and a k represents a state; Kx, ky and kz form a K space (belonging to the inverted lattice), and K corresponding to all states of crystal electrons will be uniformly distributed in a W-S primitive cell of the inverted lattice, which is called Brillouin zone. See "/xmx028@ 126/" for the description of microelectronics physics.
