This study proposes a methodology for enhancing the surface plasmon polariton (SPP) resonance associated with graphene through nanoscale metal-dielectric-metal (MDM) gaps. By tuning the carrier density in graphene, the resonances in the range of 0.7 μm to 1 μm can be modulated, which shows potential utility for surface analyte sensing. Finite element simulations in the frequency domain demonstrate that the related hybrid SPP modes can be clearly delineated in far field spectroscopy.
A methodology for enhancing the surface plasmon polariton (SPP) resonance associated with graphene, through nanoscale metal-dielectric-metal (MDM) gaps, is proposed. The modulation of the resonances, in the range of 0.7 mu m to 1 mu m was done through tuning the carrier density in graphene and has been shown to be of potential utility for surface analyte sensing. It was shown, from finite element simulations in the frequency domain, that the related hybrid SPP modes could be clearly delineated in far field spectroscopy.
