Silicon carbide has a range of attractive properties that stem from its large bandgap—the energy hurdle that must be overcome to switch from insulator to conductor. Silicon carbide’s bandgap is 3.26 electron volts to silicon’s 1.1 eV, which means the material can be exposed to significantly higher electric fields and temperatures than silicon can without breaking down.
