Researchers at the Hong Kong University of Science and Technology (HKUST) School of Engineering have cracked a major challenge in display technology by inventing the world’s brightest and most energy efficient quantum rod LEDs (QRLEDs). These next-generation QRLEDs feature optimized deep green emission at the top of the color triangle, enabling displays with unprecedented color purity and a maximized color gamut. Boasting a longer lifespan and triple the brightness of previous models, these cutting-edge light sources deliver energy-efficient, ultra-vivid ...

It is reported that Hong Kong University of Science and Technology (HKUST) has developed silicon substrate green and yellow nitride semiconductor LEDs. Details of the development were published in the May 29th issue of IEEE Electronic Device Letters. The researchers claim their 565nm yellow LEDs are the first multi-quantum well (MQW) devices produced on silicon. The researchers used metal-organic chemical vapor deposition (MOCVD) to grow the initial template, grown on 2-inch silicon. The template consisted of aluminium nitride (AlN) nucleation, 8 pai...
