Why Gallium Nitride (GaN) in Space?

Devices in satellites in orbit around our earth, or in exploration satellites visiting the most distant parts of our solar system, all experience some form of high-energy radiation bombardment. Gallium nitride (GaN) is a very hard, mechanically stable wide bandgap semiconductor. Gallium nitride is also inherently radiation tolerant, making GaN-based devices a reliable option for space applications.
