Technology

We report a significant improvement in the electrical characteristic of compositionally graded InGaN/GaN multiple-quantum-well (MQWs) micro-LED. The efficiency droop in this device occurred at similar to 20 times higher injection levels (similar to 275 A/cm(2)) compared to a conventional step-MQWs micro-LED (similar to 14 A/cm(2)).
