Abstract :
Further enhancement of the polarized emission efficiency of an InGaN/GaN single quantum well (QW) light-emitting diode (LED) with the QW coupling with surface plasmon generated on an Ag nano-grating structure on the top of the LED by inserting a SiO2 layer between semiconductor and metal is demonstrated.
