Graphene plasmonics: manipulating light at the nanoscale with a one-atom-thick material

\nSurface plasmon polaritons (SPPs), collective oscillations of the electron density coupled to electromagnetic fields at metallic surfaces, enable the confinement of electromagnetic radiation at subwavelength scales. Plasmonics, the subfield of nanophotonics that studies SPPs, leverages these capabilities to investigate the fundamental processes governing light–matter interactions and to engineer nanoscale optoelectronic devices.\n
