WebSemiconductor Band Gaps From the band theory of solids we see that semiconductors have a band gap between the valence and conduction bands. The size of the band gap … WebWide bandgap power semiconductors such as SiC or GaN can safely operate at a junction temperature of 500°C. Such a high operating temperature range can substantially relax or completely eliminate the need for bulky and costly cooling components commonly used in silicon-based power electronic systems. However, a major limitation
