In contrast, for p-type aluminium (Al)-doped SiC, an average acceptor energy level in the range of 200 to 240 meV is found for all polytypes. Other p-type dopants such as boron (B) have deeper acceptor levels (≈ 300 meV), but are not commonly used.

Doping (semiconductor) - Wikipedia

History The effects of semiconductor doping were long known empirically in such devices as crystal radio detectors and selenium rectifiers.For instance, in 1885 Shelford Bidwell, and in 1930 the German scientist Bernhard Gudden, each independently reported that the properties of semiconductors were due to the impurities contained within them.

Silicon Carbide (SiC) | Morgan Technical Ceramics

The silicon reacts with the carbon forming more SiC which bonds the initial SiC particles. Sintered SiC is produced from pure SiC powder with non-oxide sintering aids. Conventional ceramic forming processes are used and the material is sintered in an inert atmosphere at temperatures up to 2000ºC or higher.
