    Composition-dependent trapezoidal quantum barrier effect on efficiency droop in GaN-based light-emitting diodes

    We systematically investigated GaN-based light-emitting diodes (LEDs) with composition-dependent trapezoidal quantum barriers (QBs) to analyze the efficiency droop behavior at low and high current densities. T...
