Abstract

The electroluminescence efficiency at room temperature and low temperature 15 K in a widenarrowwell InGaN/GaN lightemitting diode with a narrow last well 15 nm and a narrow nexttolast barrier 5 nm is investigated to study the efficiency droop phenomenon A reduced droop in the wide wells and a reduced droop at low temperatures reveals that inferior hole transportation ability induced Auger recombination is the root for the droop at high excitation levels
