1. In three-dimensional space the Brillouin zone boundaries are planes. 2. It is the Brillouin zone of body centered cubic ( bcc ) crystals. 3. Green dashed rectangle represents the Brillouin zone of the CuO2 plane of BSCCO. 4. The dashed rectangle represents the first Brillouin zone . 5. The primitive cell of the reciprocal lattice in momentum space is called the Brillouin zone . 6. The Wigner Seitz cell in the reciprocal space is known as the first Brillouin zone . 7. High-symmetry points in the Brillouin zone belong to different point-group representations. 8. The Wigner Seitz cell of the reciprocal lattice in momentum space is called the Brillouin zone . 9. The Fermi surface therefore consists of Fermi arcs forming pockets centered on the corner of the Brillouin zone . 10. The surface Brillouin zone ( SBZ ) for phonons consists of two dimensions, rather than three for bulk.
