What is Wide-bandgap semiconductor?
Semiconductors with a larger band gap than silicon, such as SiC and GaN. Their high breakdown field makes them strong for high-voltage, high-temperature operation.
Field: Compound semiconductors
Wide-bandgap semiconductor in the explanations
About 0.66 eV is germanium, whose small gap makes leakage rise quickly at high temperature; about 3.4 eV is GaN, a wide-bandgap semiconductor suited to high voltage, high temperature and blue LEDs.
