What is Efficiency droop?
The drop in luminous efficiency of InGaN LEDs as current increases. Auger recombination is thought to be one cause.
Field: Compound semiconductors
Efficiency droop in the explanations
InGaN LED efficiency peaks at relatively low current densities of a few A/cm² and declines as current increases—efficiency droop.
What is the phenomenon called in which the efficiency of an…
