Silicon carbide MOSFETs: Superior switching technology …
2011/9/12· Silicon carbide also has a thermal conductivity 2.8X higher than silicon, providing a much higher current density at a given junction temperature than a comparably-rated silicon device. With a bandgap that is approximately 3X wider than silicon, SiC devices also exhibit significantly lower leakage current at high temperature operation – by more than two orders of magnitude.

Silicon Carbide in Cars, The Wide Bandgap …
Since its shape offers a higher symmetry, electrons ster less making it the Silicon Carbide structure with the highest maximum electron low-field mobility at room temperature (1000 cm 2 /Vs 1). On the other hand, 6H-SiC (six bilayers in a hexagonal lattice) may have less interesting electrical properties with an electron mobility of 380 cm 2 /Vs, but its lesser symmetry makes it much easier
What Is The Difference Between Alpha SiC And Beta SiC …
The crystal structure of silicon carbide is divided into hexagonal or rhoohedral α-SiC and cubic β-SiC (called cubic silicon carbide). Since α-SiC constitutes many different variants due to the different stacking sequences of carbon and silicon atoms in its crystal structure, more than 70 kinds have been found. β-SiC is converted to α-SiC at 2100 ° C or higher.
