Abstract:
1. A light emitting diode structure, the light emitting diode structure comprising a red/yellow light emitting multiple quantum well (MQW) structure, each quantum well structure of the red/yellow light emitting MQW comprising: a barrier layer; and a well layer having quantum dot nanostructures embedded therein formed on the barrier layer, the barrier and the well layer comprising a first metal-nitride based material; wherein at least one of the quantum well structures of the red/yellow light emitting MQW further comprises a capping layer formed on the well layer, the capping layer comprising a second metal-nitride based material having a different metal element compared to the first metal-nitride based material; and a blue light emitting MQW structure formed integrally with the red/yellow light emitting MQW for emitting white light from the light emitting diode structure.
