The silicon with added impurities can become N-type semiconductor or P-type semiconductor. If the impurity with five valence electrons donor (Nitrogen-N, Phosphorus-P, Arsenic-As, Antimony-Sb, Bismuth- Bi) is added to the pure tetravalent silicon, the four impurity electrons will be covalently tied up with four neighbourly Si atoms and forming covalent bonds.

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

Carbure de silicium — Wikipédia

Le carbure de silicium est un composé chimique de formule SiC. C''est une céramique réfractaire ultradure semiconductrice synthétique, qu''on peut trouver dans la nature sous la forme d''un minéral très rare, la moissanite.Grâce au procédé Acheson, depuis la fin du XIX e siècle, on sait produire industriellement de la poudre de carbure de silicium, qui servit d''abord comme abrasif.
