In recent years, GaN (gallium nitride) and SiC (silicon Carbide) based semiconductors called the "Next Generation Power Semiconductors"have been receiving much attention. Compared to silicon, GaN and SiC have a wider band gap (Si:1.1, SiC:3.3, GaN:3.4), and therefore it is also called "Wide Band Gap Semiconductors".
Gallium nitride — Wikipedia Republished // WIKI 2
Gallium nitride (GaN) is a binary III/V direct bandgap semiconductor commonly used in light-emitting diodes since the 1990s. The compound is a very hard material that has a Wurtzite crystal structure. Its wide band gap of 3.4 eV affords it special properties for appliions in optoelectronic, high-power and high-frequency devices. For example, GaN is the substrate which makes violet (405 nm
