Pseudo-substrates Promise To Produce Better Red MicroLEDs

By reducing strain with an InGaN layer on a buried oxide, red-emitting InGaN-based microLEDs are tipped to yield higher efficiencies While phosphide-based structures lead the way for making most red LEDs, their performance plummets as dimensions decrease. When shrunk below 10 µm, which is the size these microLEDs need to be for displays for virtual and augmented reality, losses are exacerbated by long carrier diffusion lengths and a high density of surface defects at sidewalls. Pioneering an alternative is a French partnership between the University of Gren...
