Silicon carbide has a variety of crystal types, but the silicon crystal structure the market needed is mainly 4H-SiC. So the silicon carbide crystal growth in crystal types is a defect. To a certain extent, it can be distinguished by the naked eye. A more accurate measurement method for testing [...]
