10 Things To know About SiC - Power Electronics News

17/3/2021· In its pure form, silicon carbide behaves like an electrical insulator. With the controlled addition of impurities or dopants, SiC can behave like a semiconductor. A P-type semiconductor can be obtained by doping it with aluminum, boron, or gallium, while impurities of nitrogen and phosphorus give rise to a N-type semiconductor.

Semiconductor - Wikipedia

Certain pure elements are found in Group 14 of the periodic table; the most commercially important of these elements are silicon and germanium. Silicon and germanium are used here effectively because they have 4 valence electrons in their outermost shell which gives them the ability to gain or lose electrons equally at the same time.
