What are SiC Semiconductors? ＜SiC＞ | Electronics Basics | ROHM
Physical Properties and Characteristics of SiC. SiC (silicon carbide) is a compound semiconductor composed of silicon and carbide. SiC provides a nuer of advantages over silicon, including 10x the breakdown electric field strength, 3x the band gap, and enabling a wider range of p- and n-type control required for device construction.
Production. Due to the rarity of natural moissanite, silicon carbide is typically man-made. Most often it is used as an abrasive where it is often known by the trademark carborundum, and more recently as a semiconductor and diamond simulant of gem quality. The simplest manufacturing process is to coine silica sand and carbon in an Acheson graphite electric resistance furnace at a high
