Figure. The Brillouin zone for cubic lattices: (a) SC,(b) FCC, and (c) BCC. The irreducible part of the zone is also shown. (The shape of the Brillouin zone of the scc lattice is identical to the shape of the Jones zone for the diamond/zincblende structure crystals. SC A general...
The first Brillouin zone for the bcc lattice. 1.10.5 fcc Lattice The primitive translation vectors b1,b2,b3 of the reciprocal lattice of the fcc lattice are (Problem 1.14) (1.58)b1=(2π/a)(yˆ+zˆ−xˆ),b2=(2π/a)(zˆ+xˆ−yˆ),b3=(2π/a)(xˆ+yˆ−z...
