Efficiency and Forward Voltage of Blue and Green Lateral LEDs with V-shape defects and Random Alloy Fluctuation in Quantum Wells

Cheng-Han Ho, James S. Speck, Claude Weisbuch +1

For nitride-based blue and green light-emitting diodes (LEDs), the forward voltage $V_{\text{for}}$ is larger than expected, especially for green LEDs. This is mainly due to the larg…
