Za Silicon Carbide (SiC)Crystal
Silicon carbide (SiC), yomwe imadziwikanso kuti carborundum, ndi semiconductor yokhala ndi silicon ndi kaboni yokhala ndi fomula yamankhwala SiC.SiC imagwiritsidwa ntchito pazida zamagetsi za semiconductor zomwe zimagwira ntchito kutentha kwambiri kapena kutentha kwambiri, kapena zonse ziwiri.SiC ndi chimodzi mwazinthu zofunika kwambiri za LED, ndi gawo lodziwika bwino lazida za GaN, komanso limagwira ntchito ngati chofalitsa kutentha m'malo okwera kwambiri. magetsi a LED.
