Abstract :
The growths and characteristics of staggered InGaN quantum wells (QWs) and type-II InGaN-GaNAs QWs are presented for high-efficiency green-emitting light-emitting diodes (LEDs). Approaches for enhancing internal-quantum-efficiency, light-extraction-efficiency, and efficiency-droop in nitride LEDs are discussed.
