  • Abstract
    GaN- and AlN-based light-emitting diodes (LEDs) suffer from a severe efficiency reduction with increasing injection current (droop). Based on different theoretical models, several physical mechanisms have been proposed to explain the efficiency droop; however, conclusive experimental evidence is still missing for these proposals, and none of them is generally accepted. This presentation reviews and evaluates the main efficiency droop models currently under consideration.
