Abstract:Investigation of surface plasmon coupling with the quantum well for reducing efficiency droop in GaN-based light emitting diodes J. Appl. Phys. 114, 113104 (2013) A light emitting active region with three InGaAs quantum wells is monolithically integrated with a GaAs hemisphere as a means to increase the extraction efficiency of light emitting diodes. For a device with a small active region and large hemisphere and optimal antireflection, theoretical calculations show that the extracted fraction of spontaneous … Show more
