This study demonstrates a localized surface plasmon (LSP) coupling nanorod mu LED with graphene as a transparent conductive electrode structure. The mu LED with LSP coupling shows an enhancement of about 36% in external quantum efficiency and 84% in photoluminescence measurements compared to the LSP-free sample. This enhancement is achieved through the large sidewall area provided by the nanorod structure and the zero distance contact between the nanoparticles and nanorods.
A localized surface plasmon (LSP) coupling nanorod mu LED using graphene as a transparent conductive electrode structure was demonstrated. The optical performance of the mu LED with LSP coupling is enhanced by about 36% in external quantum efficiency and 84% in photoluminescence measurements as compared with the LSP-free sample. This LSP coupling enhancement relies on the very large sidewall area provided by the nanorod structure and the zero distance contact between the nanoparticles and nanorods. This work provides a broad prospect for the application of LSP in the mu LED field.
