Gallium nitride is a semiconductor tipped for a bright future. Already widely employed as a light source – being used to illuminate London’s Buckingham Palace and other European landmarks – its high power capacity could spark a space-based communications revolution, promising a five- to ten-fold improvement in satellite signal strength and data rates.
Generally regarded as the most promising semiconductor since silicon, gallium nitride (GaN) works better at much higher voltages and temperatures than silicon or the widely-used gallium arsenide (GaAs). Significantly for space, GaN is also inherently radiation-resistant.
