About Silicon Carbide (SiC)Crystal
Silicon carbide (SiC), also known as carborundum, is a semiconductor containing silicon and carbon with chemical formula SiC. SiC is used in semiconductor electronics devices that operate at high temperatures or high voltages, or both.SiC is also one of the important LED components, it is a popular substrate for growing GaN devices, and it also serves as a heat spreader in high-power LEDs.
