Plasmonic Enhancement in InGaN/GaN MQW System with Au Nanoparticles

Keywords: , , ,

In this article we report experimental evidence of plasmon based enhancement of an InGaN/GaN MQW system using Au nanocrystals. Enhancement of the main peak along with a blue-shift and change in the angle dependent PL suggests off-peak coupling of the plasmons resulting in enhancement. Near-field Microscopy of the samples clearly shows the enhancement and blue-shift in the region of the Au NC’s. Results of both Temperature and Angle dependent far field microscopy provide further data suggesting the involvement of plasmons in the sample’s enhancement.
