Kubos Semiconductors from the UK and the UK Compound Semiconductor Centre (CSC) announced that their partnership to commercialize cubic GaN epitaxy for the manufacture of high efficiency green and amber LEDs. Hexagonal GaN crystals have been widely used to fabricate blue LEDs, but achieving efficient operation in green devices is a problem. Large polarization fields in the active regions of these longer-wavelength structures reduce radiative recombination rates and limit LED efficiency. Targeting the issue, Kubos Semiconductors develops process based on gr...
