摘要: The Auger recombination is recently proposed as
one of the possible origins for the deteriorated internal quantum
efficiency of InGaN light-emitting diodes. The Auger
recombination behavior is quite different under widely varied
Auger coefficients. The effect of Auger coefficient on
the efficiency and output power is investigated numerically.
The simulation results indicate that the Auger recombination
with large Auger coefficient greatly decreases the efficiency
in the whole current range under study. It is found that the
electron current leakage and nonuniform hole distribution
are the possible mechanisms responsible for the efficiency
droop at high injection current.
