The Wide Bandgap Revolution

The Wide Bandgap Revolution

The bandgap is the region between the valence band and the conduction band in an atom.
The wider it is, the more energy it takes to push an electron into the conduction band.

Wide Bandgap Materials

Wide Bandgap Materials

The category of electronic materials in which the bandgap energy exceeds approximately 2 electronvolts (eV).

Conventional semiconductors are made of

Wide Bandgap Applications

Wide Bandgap Applications

This means improvements in a wide range of applications


WBGSs are used in the traction inverter and for Level 3 charging of electric vehicles.

Renewable Energy

With WBGSs energy conversion efficiency increases by around 85%.


WBGSs contribute to more efficient power in railway systems, manufacturing, power plants and more.

Communication Infrastructure

WBGSs can also be used in radio frequency (RF) signal processing, and switching is faster and more high-power.

Aerospace & Defense

SiC and GaN are inherently radiation hardened (rad-hard) and have high-temperature operating capabilities, making them suitable for aerospace applications.
