Distributed Bragg reflector (DBR) and charge asymmetric resonance tunneling (CART) structures were applied to nitride-based green light-emitting diodes (LEDs) to enhance their output efficiency It was found that we can reduce the forward voltage at 20 mA from 3.7 to 3.2 V with the inclusion of CART structure. It was also found that the electroluminescence peak wavelength of the CART LED is less sensitive to the amount of injection current. The output power and external quantum efficiency of the CART LED with DBR structure measured at 20 mA can reach 7.2 mW and 11.25%, respectively
