Abstract :
We obtained strong near-UV and blue emissions at room temperature from In-rich InGaN/GaN MQW structures. We believe that use of less than 2-nm-thick In-rich InGaN QW layer can be a new candidate for near-UV and visible sources, which might replace the conventional Ga-rich, thicker InGaN QW layer.
