Based on the ABC model, we derive a relationship between the internal quantum efficiency (IQE) and the width of the efficiency-versus-carrier-concentration curve. We determine the IQE of LEDs at temperatures ranging from 100K to 300K.
The efficiency droop in GaInN light-emitting diodes (LEDs) is an impediment for the introduction of solid-state lighting technology. The origin of the droop will be discussed along with measures that mitigate the droop.
