Abstract

We report the white color electroluminescence (EL) emission from InGaNGaN multiple quantum wells (MQWs) grown on GaN microfacets. The white color was realized by combining EL emission from InGaNGaN MQWs on c -plane (0001), semipolar {11-22}, and {1-101} microfacets of trapezoidal n-GaN arrays. The color of EL emission was changed from reddish to bluish color with injection current and showed a white color in the current range of 180-230 mA. The variation in the color of EL emission was attributed to differences in current injection and quantum efficiency of MQWs grown on c -plane (0001) and semipolar GaN microfacets.
