India, Sept. 22 -- CEA-Leti and the Centre for Research on Heteroepitaxy and its Applications (CRHEA) announced the R&D results that have cleared a path toward full-color microdisplays based on a single material system, a long-standing goal for augmented and virtual reality (AR/VR) technologies.

The project, presented in a paper published in Nature Communications Materials, developed a technique for growing high-quality InGaN-based quantum wells on sub-micron nanopyramids, enabling native emission of red, green, and blue (RGB) light from a single material system. Titled "Regular Red-Green-Blue InGaN Quantum Wells With In Content Up To 40% Grown on InGaN Nanopyramids", the paper will be presented at the MicroLED Connect Conference on Sept...
