The volume of the parallelepiped defined by Ωrl=2(2π/a)3 Notice that the reciprocal lattice of the FCC direct space lattice is BCC, and vice versa. The reciprocal of the SC direct space lattice remains SC. It can be verified that the reciprocal lattice of the reciprocal lattice is ...
It is the unit cell of the reciprocal lattice consisting of all points in reciprocal space which are closer to the origin than to any other point of the reciprocal lattice. From: Encyclopedia of Condensed Matter Physics, 2005 About this pageSet alert ...
2.2 Reciprocal lattice of graphene The lattice obtained by applying Fourier transform to the direct lattice is termed as the ‘reciprocal lattice’. Obtained only by applying Fourier transform to the direct lattice, the reciprocal lattice is also hexagonal in structure, and its primitive unit cell ...

Reciprocal Space TechniquesSpecial PointsFermi Surface SamplingWe describe the special-point technique to integrate a periodic function over the BZ. The method of Monkhorst and Pack for special-point generation is explained and an example of its application to the fcc lattice is discussed. Several ...
As an example, we unfold the first-principles Berry curvature of an ordered Fe3Co alloy from the original fcc-lattice Brillouin zone onto a bcc-lattice zone with four times the volume. Comparison with the virtual-crystal Berry curvature clearly reveals the symmetry-breaking effects of the ...
Using this information, one eliminates the “forbidden” reflections to produce a reciprocal lattice which accurately reflects the potential diffraction conditions for a given sample. Figure 30.5 shows the [001]/[110] cross section of reciprocal lattice for a standard face-centered cubic (FCC) ...
