Silicon Carbide as a Semiconductor | Wolfspeed
Semiconductors can be made from pure elements, with Silicon and Germanium being the most common; however, they can also be made from compounds like Silicon carbide (SiC) or Gallium arsenide (GaAs). The earliest semiconductor devices were primarily made from Germanium but, later on, Silicon (Si) became the most widely used semiconductor material.
