Abstract

Simulation results of InGaN light-emitting diodes and efficiency droop are presented. A special method for investigating the changes in the semiconductor devices characteristics due to different influencing factors is developed.

The cause of efficiency droop was detected-large difference in carrier lifetimes. The simulation results are used to suggest several techniques for improving LED efficiency up to 10-15 %.
