Webthe primitive lattice vectors for the lattice you are using, e.g. when you are using a bcc lattice you usually use the primitive lattice vectors of the conventional cubic lattice as basis vectors in terms of which to describe the locations of atoms in the basis. Make sure you understand what you are writing down, and write it down clearly.] 1 WebA reciprocal lattice is a periodic set of points in this space, and contains the points that compose the Fourier transform of a periodic spatial lattice. The Brillouin zone is a volume within this space that contains all the unique k-vectors that represent the periodicity of classical or quantum waves allowed in a periodic structure.
