WebAug 29, 2024 · SiC (silicon carbide) is a compound semiconductor composed of silicon and carbide. SiC provides a number 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 needed for device construction. SiC also has a very low coefficient of thermal expansion (4.0 × 10 −6 /K) and experiences no phase transitions that would cause discontinuities in thermal expansion. Electrical conductivity. Silicon carbide is a semiconductor, which can be doped n-type by nitrogen or phosphorus and p-type by beryllium, … See more Silicon carbide (SiC), also known as carborundum (/ˌkɑːrbəˈrʌndəm/), is a hard chemical compound containing silicon and carbon. A semiconductor, it occurs in nature as the extremely rare mineral moissanite, … See more Early experiments Non-systematic, less-recognized and often unverified syntheses of silicon carbide include: See more Silicon carbide exists in about 250 crystalline forms.
