Abstract

The influence of nitride heterostructures on efficiency droop is presented. It was developed a special method based on simulation for investigating the changes in the semiconductor devices characteristics due to different influencing factors. The cause of efficiency droop was detected - large difference in carrier lifetimes. The simulation results are used to suggest several ways for improving LED efficiency about 12 %.
