The luminous efficiencies of green lights are still not enough. InGaN/GaN QWs grown on semipolar plane such as {11-22} planes have been developed and studied to overcome this “green-gap problem” of LEDs. Surface plasmon (SP) resonance is also promising method to apply to high-efficiency LEDs.
In this study, we compared and investigated the SP enhanced light emissions of silver / aluminum-coated polar / semipolar InGaN / GaN quantum wells (QW) and the emission mechanisms.
