The plane-wave pseudopotential approach to density-functional theory (DFT) in the local-density approximation has been applied to investigate a variety of ground-state properties of the 3C, 2H, and 4H polytypes of silicon carbide. The linear-response theory within DFT has been used to obtain lattice-dynamical properties of cubic SiC such as the phonon-dispersion curves, phonon eigenvectors

Bringing silicon carbide to the masses - News
When 3C-SiC is grown on a silicon (111) substrate, this produces the ideal template for hexagonal GaN, due to a lattice mismatch of approximately 3.5 percent at the SiC-silicon interface. Reducing mismatch between GaN and silicon is valued highly, because it holds the key to reducing the intrinsic defects found in GaN when this material is grown on highly mismatch substrates, such as silicon

The crystal lattice of silicon can be represented as two penetrating face centered cubic lattices (fcc) with the cube side a =0.543nm as portrayed in Figure 3.1. The structure is visualized as a tetrahedron with four vertices of the first fcc lattice at (0,0,0), ( a /2,0,0), (0, a /2,0) and (0,0, a /2) and an additional atom added to the center of this tetrahedron.
