WebDec 27, 2024 · (I thought they both gave hexagonal lattices but the rhomic unit cell with two rods gives a honeycomb lattice wheras hexagonal unit cell with one rod gives a hexagonal lattice). ... First, the reciprocal lattice vectors $\bar a,\bar b,\bar c$ can be calculated from the direct ... This Brillouin zone could be reduced further depending on the ... WebThe first Brillouin zone of an bcc lattice has the same shape (a rhombic dodecahedron) as the Wigner-Seitz cell of a fcc lattice. Some crystals with an bcc Bravais lattice are Li, Na, K, Cs, V, Cr, Fe, Nb, Mo, Rb, Ba, Ta. Another applet that shows the bcc real space and reciprocal space lattices.
