摘要：

Nitride-based light-emitting diodes (LEDs) with Mg-doped In0.23Ga0.77N capping layers were successfully fabricated. Compared to Mg-doped GaN layers, it was found that we could achieve a much larger hole concentration from Mg-doped In0.23Ga0.77N layers. It was also found that we could reduce the 20 mA operation voltage from 3.78 to 3.37 V by introducing a 5-nm-thick In0.23Ga0.77N layer on top of the p-GaN layer. Furthermore it was found that output intensity of LEDs with In0.23Ga0.77N capping layer was much larger, particularly at elevated temperatures.
