Gallium nitride (GaN) offers fundamental advantages over silicon. In particular, the higher critical electrical field makes it very attractive for power semiconductor devices with outstanding specific dynamic on-state resistance and smaller capacitances compared to silicon MOSFETs, which makes GaN HEMTs great for high speed switching.

Gallium oxide's bandgap is about 4.8 electron volts, which places it among an elite group of materials considered to have an ultrawide bandgap. The bandgap of these materials exceeds that of silicon (1.1 electron volts), the most common material in power electronics, as well as potential replacements for silicon, including silicon carbide (about 3.4 electron volts) and gallium nitride (about
Aluminum Gallium Nitride AlGaN has attracted more attention in III-nitride alloys due to the unique characteristics of AlGaN/GaN heterojunctions ( Strite and Morko, 1992; Morko, 2001 ). AlGaN/GaN has a large lattice mismatch, and V-shaped cracks would form when AlGaN was grown on
