Diamond''s cubic structure is in the Fd 3 m space group, which follows the face-centered cubic Bravais lattice.The lattice describes the repeat pattern; for diamond cubic crystals this lattice is "decorated" with a motif of two tetrahedrally bonded atoms in each primitive cell, separated by 1 / 4 of the width of the unit cell in each dimension.
Where h is the Planck constant, γ is the electron gyromagnetic ratio (≈ 2.8 MHz/G), B is the external magnetic field vector, and D is the zero-field splitting tensor. In the absence of lattice strain, the VV spin-spin interaction simplifies to !!!!! where D 0 ~ 1.336 and

i ABSTRACT Silicon carbide (SiC) has always been considered as an excellent material for high temperature and high power devices. Since SiC is the only compound semiconductor whose native oxide is silicon dioxide (SiO 2), it puts SiC in a unique position.), it puts SiC in a unique position.

Silicon carbide occurs in many different crystal structures, called polytypes. A comprehensive intro-duction to SiC crystallography and polytypism can be found in Ref. 10. Despite the fact that all SiC polytypes chemically consist of 50% carbon atoms covalently
Silicon Carbide – SiC Silicon carbide was discovered in 1893 as an industrial abrasive for grinding wheels and automotive brakes. About midway through the 20 th century, SiC wafer uses grew to include in LED technology. Since then, it has expanded into numerous
Abstract: We present an analytical bond-order potential for silicon, carbon, and silicon carbide that has been optimized by a systematic fitting scheme. The functional form is adopted from a preceding work [Phys. Rev. B 65, 195124 (2002)] and is built on three independently fitted potentials for Si …

This high-temperature treatment leads to the formation of cubic beta silicon carbide, which differs from the well-known alpha silicon carbide in certain important aspects. Not only is the crystallographic structure different (hexagonal in case of alpha versus cubic in case of Beta SiC), but also properties effected by the atomic lattice like fracture and wetting characteristics.
