The world’s highest-efficiency LED lightbulbs and solid state electrical power converters require single-crystal GaN substrates (wafers), which today cost >$3,000 apiece (for a 2” wafer). We are developing a process to produce GaN substrates better than those available today for <$100 apiece, thereby reducing the costs of these high-efficiency devices to enable mass adoption. We expect that significant energy savings will be realized through the proliferation of lower cost, higher efficiency LEDs and power conversion devices.
