Apart from crystal quality, problems with the interface of SiC with silicon dioxide have hampered the development of SiC-based power MOSFETs and insulated-gate bipolar transistors. “The issue is, ‘what’s occurring in China?�?China is by now main in terms of raw material for silicon carbide, and they're delivering very high-quality, reasonably https://www.quora.com/profile/Trevor-Flatcher-2/Role-of-Silicon-Carbide-in-Fuel-Cells-Silicon-carbide-SiC-plays-a-crucial-role-in-advancing-fuel-cell-technology-off
