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 the original direct space lattice. ...
Figure 1.13 shows the relationships between the Brillouin zones for the (111), (110), and (001) planes of the fcc and bcc lattices and their respective bulk Brillouin zones. Various points and lines in Brillouin zone are related to each other by the symmetry operations of the lattice listed...
2.3 Intrinsic Broadening of Reciprocal Lattice Point Using the basic diffraction principles, we have only illustrated the influence of crystal imperfections on the broadening of reciprocal lattice points. This does not mean that the reciprocal lattice point of a perfect crystal is a geometrical point ...
lattice, are: b 1 = 2π a (−e x + e y + e z ) b 2 = 2π a (e x −e y + e z ) b 3 = 2π a (e x + e y −e z ) These are primitive translation vectors of a bcc lattice, so that the bcc lattice is reciprocal to the fcc lattice. The volume of the ...

Coincidence of reciprocal lattice point (CRLP) model was used to predict the stable orientation relationships of metal/伪-Al_2O_3 hetero interfaces from geometrical considerations. The predicted stable orientation relationships (ORs) between various metals and a-Al_2O_3 agreed well with the ...

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 ...
