Gallium nitride - Wikipedia
Gallium nitride (Ga N) 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 applications in optoelectronic, high-power and high-frequency devices. For example, GaN is the substrate which makes violet (405 nm ...

UCSB College of Engineering professors Steven DenBaars, Umesh Mishra, and James Speck began working with gallium nitride (commonly referred to as GaN) as a semiconductor in 1993, but at the time, funding for such research was largely unavailable because, as DenBaars recalls, “GaN was thought to be useless as a semiconductor.”. That was because GaN is a highly imperfect crystal.
