What is the primary advantage of using a Gallium Nitride (GaN) semiconductor over traditional silicon in power electronics ?
Greater thermal stability
GaN is a wide-bandgap semiconductor: its bandgap is about 3.4 eV against 1.12 eV for silicon. It also has a very high critical breakdown field (about 3.3 MV/cm).
The wide bandgap means intrinsic carrier generation stays negligible up to much higher temperatures, so GaN devices keep working reliably at high junction temperatures and high power densities – that is, they offer greater thermal stability than silicon in power electronics.
A “lower bandgap” is the opposite of the truth, since GaN’s bandgap is about three times that of silicon.
Hence, the primary advantage of GaN over silicon in power electronics is Greater thermal stability.
