Why Use GaN Wafers?
Gallium Nitride on sapphire is the ideal material for radio energy amplification. It offers a number of benefits over silicon, including a higher breakdown voltage and better performance at high temperatures.
GaN is a binary III/V direct bandgap semiconductor commonly used in bright 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
