InGaN/GaN multiple quantum well(MQW)light-emitting diodes(LEDs)have attractedwidespread attention for their potential applications in next generation solid state *** years,efforts were made to overcome the “green gap” of MQW structures,which is thatthe internal quantum efficiency(IQE)of their emission drops dramatically when the wavelengthextends from blue to green range.
