Abstract
Graphene and 2D materials have gathered great attention lately, due to its property of interface modification. Combining graphene with metals, it would be able to modulate the carrier concentration of metals and also plasmon frequency. In this abstract, the variation of Vg and plasma frequency (ωp) have been demonstrated successfully on gold films with graphene and without graphene. Forward scattering spectra of the slit-groove structures exists Fabry-Perot interference. This work could extend to the graphene modulated nanophotonics devices [1]. For example, the SPPs propagate on the graphene-metal surface can be utilized to develop graphene-plasmonic waveguide [2].
