A critical look at the SiC, high-voltage MOSFET - News
Due to the unipolar nature of this device, it does not suffer from a dynamic avalanche limitation that impairs safe-operating area capability "“ note that this does hamper the silicon IGBT. What''s more, the SiC MOSFET has a higher junction built-in voltage, so, compared to its silicon cousin, it has extra protection against parasitic n-p-n transistor failure modes during switching.

acceptable for prediction of device behavior in 4H-SiC. Figs. 5 and 6 show the comparison of the output char-acteristics of 4H- and 6H-SiC MOSFET at 300 K and transfer characteristics at diﬀerent temperature, respec-tively. Simulation results show that the drain
Review article: silicon carbide. Structure, properties and …
Silicon carbide: structure, some properties, and polytypism. The fundamental structural unit of silicon carbide is a covalently bonded primary co-ordinated tetrahedron, either SiC 4 or CSi 4.
Silicon Carbide SiC Material Properties
Silicon carbide ceramics with little or no grain boundary impurities maintain their strength to very high temperatures, approaching 1600 C with no strength loss. Chemical purity, resistance to chemical attack at temperature, and strength retention at high temperatures has made this material very popular as wafer tray supports and paddles in semiconductor furnaces.
