摘要: Abstract We have investigated efficiency droop in InGaN-based blue LEDs by considering radiative, nonradiative, and carrier spillover processes the context of internal quantum (IQE) vs. injection current. If relied on fitting only, both Auger recombination an empirical formula for are consistent with experiments. However, dependence IQE well parameters lack optical pumping experiments support notion that is main mechanism play.
