The Efficiency Improvement of Blue InGaN Multiple Quantum-Well Light-Emitting Diodes with AlGaN/InGaN Superlattice Barriers
-
Abstract
The characteristics of blue InGaN light emitting diodes with AlGaN/InGaN superlattice barriers are investigated. The efficiency droop can be improved when AlGaN/InGaN superlattice barriers are used. This improvement can be attributed to the reduced polarization effect in the active region by using AlGaN/InGaN superlattice barriers.
