Wide Bandgap Semiconductors (WBG semiconductors) are a class of advanced electronic materials characterized by a larger energy bandgap compared to traditional semiconductors such as silicon. This wider bandgap typically allows these materials to operate at higher voltages, temperatures, and frequencies, making them highly suitable for demanding modern applications. The most commonly used wide bandgap materials include Silicon Carbide (SiC) and Gallium Nitride (GaN), both of which have gained significant traction in power electronics, RF (radio frequency) systems, and next-generation energy-efficient devices.
