Tunable Properties of Three-Dimensional Graphene-Loaded Plasmonic Absorber Using Plasmonic Nanoparticles

Article Preview

Abstract:

We demonstrate a three-dimensional nanostructure design by combining graphene and conventional plasmonic nanostructures, to achieve the high absorbance in the visible region. Furthermore, the peak position and bandwidth of graphene absorption spectra are tunable in a wide wavelength range through a specific structural configuration. Comparing the results of two structures which is based on different materials, Gold and Silver. The structure made of Silver present a better performance. These results imply that graphene in combination with plasmonic perfect absorbers have a promising potential for developing advanced nanophotonic devices.
