  • Abstract
    A nitride-based asymmetric two-step light-emitting diode (LED) with In0.08 Ga0.92N shallow step was proposed and fabricated. It was found that the low indium content In0.08 Ga0.92N layer can significantly enhance phase separation and/or inhomogeneous indium distribution in the active In0.27Ga0.73N layer. It was also found that we can enhance LED output power by a factor of 2.27 by simply inserting an In0.08 Ga0.92N shallow step.
