WebSince the brillouin zone is constructed by inverting the lattice vectors, the brillouin zone is shaped based upon the lattice, but not the basis. If you consider a single point and repeated apply the lattice vectors of graphene, what you will get is a hexagonal crystal which is different than graphene's honeycomb structure. WebMay 22, 2024 · 6.15: The first Brillouin zone. Since there are only N distinct values of the coefficients (corresponding to one period of the Fourier transform), we typically restrict k …
WebThat is if you Fourier transform fcc lattice, then you would get bcc, body centered cubic lattice, and therefore the force to Brillouin zone for these crystals will be the unit cell of a body centered cubic lattice. And the unit cell of a body centered cubic lattice is shown in this diagram here and it is a truncated octahedron.

The probability density shoots up at the scatterer locations. (b) and (d), Local Fourier transforms of the wave function for three scatterer locations.
The Brillouin zone (purple) and the Irreducible Brillouin zone (red) for a hexagonal lattice. There are also second, third, etc., Brillouin zones, corresponding to a sequence of disjoint regions (all with the same volume) at increasing distances from the origin, but these are used less frequently. See more In mathematics and solid state physics, the first Brillouin zone is a uniquely defined primitive cell in reciprocal space. In the same way the Bravais lattice is divided up into Wigner–Seitz cells in the real lattice, the See more • Kittel, Charles (1996). Introduction to Solid State Physics. New York: Wiley.
