WebSilicon carbide (SiC) is an attractive power semiconductor possessing favorable physical properties such as a wide band-gap and a high thermal conductivity. Top-Seeded Solution Growth (TSSG) method is a promising technique for producing high-quality SiC single crystals. In the TSSG method of SiC, solid Si is heated and melted in the graphite WebGrowth and Properties of β‐SiC Single Crystals. Chemical, electrical, and optical measurements were performed on n‐ and p‐type β‐silicon carbide crystals grown from pure or doped carbon‐saturated silicon melts. Pure, transparent yellow crystals showed no detectable impurities and had carrier concentrations in the range of 1016 cm−3.
