Silicon Carbides - an overview | ScienceDirect Topics

Silicon carbide (SiC) has been recognized as a promising semiconductor material for high-temperature and high-power electronics because of its wide band gap and high breakdown field. SiC has many polytypes (e.g., 3C, 6H, 4H, and 15R), which display little difference in total energy, making them difficult to control in films.
