Abstract
Recently, we succeeded in producing for the first time, 1-cd-brightness blue InGaN/AlGaN light-emitting diodes (LEDs) suitable for commercial applications.1,5 In this report, co-doping with both Zn and Si into the InGaN active layer in InGaN/AlGaN LEDs in order to increase the output power of the InGaN/AlGaN LEDs is described.
