  • Abstract
    Gallium Nitride based light-emitting diodes (LEDs) are on the verge of enabling mainstream solid-state lighting. Their efficiency, however, is limited by a phenomenon known as droop which quenches internal quantum efficiency at high current density. We will review recent experimental results characterizing droop, and compare them to the various theories proposed these last years to explain this phenomenon.
