    摘要: A light emitting diode (LED) device structure with a reduced Droop effect, and a method for fabricating the LED device structure. The LED is a III-nitride-based LED having an active layer or emitting layer comprised of a multi-quantum-well (MQW) structure, wherein there are eight or more quantum wells (QWs) in the MQW structure, and more preferably, at least nine QWs in the MQW structure. Moreover, the QWs in the MQW structure are grown at temperatures different from barrier layers in the MQW structure, wherein the barrier layers in the MQW structure are grown a temperatures at least 40° C. higher than the QWs in the MQW structure.
