Abstract

Green tunnel-junction (TJ) light-emitting diodes (LEDs) are investigated theoretically in this letter. The influence of Auger recombination on the optical performance of green single LED and TJ LED is explored. Simulation results show that non-uniform carrier distribution and Auger recombination are critical issues influencing the performance of conventional green LED. The TJ LED can be operated at relatively low current density that possesses suppressed Auger recombination and high quantum efficiency when compared with its single LED counterpart at the same level of output power. Simulated wall-plug efficiency of the TJ LEDs with two and three unit LEDs is increased from 5.67% to 10.51% and 12.54%, respectively, in comparison with the single LED when the output power is 21 mW.
