2004/9/1· The interstitial and vacancy mediated boron diffusion in silicon carbide is investigated with an ab initio method. The boron interstitials in p -type and n -type materials are found to be far more mobile than the boron-vacancy complexes. A kick-out mechanism and an interstitialcy mechanism govern the diffusion in p -type/intrinsic and n -type material, respectively. A comparison of activation

Silicon carbide - Wikipedia

Pure silicon carbide can be made by the Lely process, in which SiC powder is sublimed into high-temperature species of silicon, carbon, silicon dicarbide (SiC 2), and disilicon carbide (Si 2 C) in an argon gas aient at 2500 C and redeposited into flake-like single crystals, sized up to 2 × 2 cm, at a slightly colder substrate.
