US researchers have patented a way to make cubic GaN for LEDs, which show promise for bridging the ‘green gap’ – the spectrum of visible light for which no efficient semiconductor emitter exists. InGaN/GaN materials emit efficiently at shorter wavelengths, and AlInGaP at longer wavelenghts. Not only might they bridge the green gap, but the ...
