Novel staggered InGaN quantum wells (QWs) and type-II InGaN-GaNAs QWs with improved momentum matrix element lead to improved internal quantum efficiency for green-emitting light-emitting diodes (LEDs). Approaches for enhancing internal quantum efficiency, light extraction efficiency, and efficiency-droop in nitride LEDs are discussed.
