Nitride-Based MicroLED Emits Pure Red Light

A microLED developed at KAUST is able to efficiently emit pure red light and could help in the quest to develop full-color displays based on a single semiconductor. MicroLEDs are a favored technology for next-generation displays, given their (small) size and energy efficiency. However, each LED is only able to emit light over a narrow range of colors. Devices can be created that combine many different LEDs that each emit a different color. Full-color displays can be created by combining red, green, and blue (RGB) microLEDs. The microLED was developed in KAUST's nanofabrication core lab. Courtesy of Anastasia Serin, KAUST. The problem, however is that an LED’s emission color is determined by the material properties of the...
