Gold/graphene fractals as tunable plasmonic devices

Graphene, an atomically thin sheet of carbon atoms arranged in a honeycomb geometry, is attracting unique attention thanks to its extraordinary mechanical, electrical and optical properties. This thesis work concerns the realization of graphene-based nanoscale devices for novel plasmonic applications. We focus mainly on gold/graphene (Au/G) structures designed to display plasmonic multiresonances in the visible range thanks to the nanostructure geometry based on the Sierpinski carpet (SC) deterministic fractal
