Although the theory of lattice dynamics was established six decades ago, its accurate implementation for polar solids using the direct (or supercell, small displacement, frozen phonon) approach within the framework of density-function-theory-based first-principles calculations had been a challenge until...

The symmetry properties of crystals have been discussed. The most common crystal structures for semiconductors have been described. We have also introduced the concept of the reciprocal lattice. We have shown that for every periodic lattice in real space \\( \\overrightarrow R \\) , it is ...
4–0.5, 0, 0) in the reciprocal lattice unit is favored for the other compounds [27], [29], [30]. We have to consider the modification of Jex(qmag), which is potentially sensitive to subtle details of the band structure in the present semimetallic materials. We also note that the ...
from these parametrizations can be computed as [9], (2)RT=∑iniai(3)ni=−12π∮Cidk⋅∇kArg[detRk] where i is the number of Bravais primitive vectors ai, the ni are the corresponding topological winding numbers, and Rk is the reciprocal rigidity matrix of a given lattice. More...
The small effective wave vector k can be interpreted as a Bloch wave vector shifted by a reciprocal lattice vector G, but not necessarily shifted into the 1 BZ and at the nBZs, edges assumes either the value k = (π/a, 0) for n odd with n = 1, 3, … or the value k = (2...
Carbon is considered to exist in three basic forms: diamond, graphite/graphene/fullerenes, and carbyne, which differ in a type of atomic orbitals hybridization. Since several decades the existence of the fourth basic carbon allotropic form with the face-centered cubic (fcc) crystal lattice has bee...
