Status of silicon carbide (SiC) as a wide-bandgap

Silicon carbide (SiC), a material long known with potential for high-temperature, high-power, high-frequency, and radiation hardened appliions, has emerged as the most mature of the wide-bandgap (2.0 eV ≲ E g ≲ 7.0 eV) semiconductors since the release of commercial 6H SiC bulk substrates in 1991 and 4H SiC substrates in 1994. Following a brief introduction to SiC material properties

Carbon - Wikipedia

2019-5-15 · Carbon (from Latin: carbo "coal") is a chemical element with syol C and atomic nuer 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. It belongs to group 14 of the periodic table.[13] Three isotopes occur naturally, 12C and 13C being stable, while 14C is a radionuclide, decaying with a
