Ag NPs are placed in close proximity to graphene which leads to additional tunable loss for the plasmon resonance. The ionic gating of graphene modifies its Fermi level from 0.2 to 1 eV, which then affects the absorption of graphene due to Pauli blocking. Plasmon resonance frequency and linewidth of Ag NPs can be reversibly shifted by 20 and 35 meV, respectively. The coupled graphene-Ag NPs system can be classically described by a damped harmonic oscillator model. Atomic layer deposition allows for controlling the graphene-Ag NP separation with atomic-level precision to optimize coupling between them.EnglishAtomic layer depositionOscillators (electronic)Oscillators (mechanical)PlasmonsResonanceSilverSurface plasmon resonanceTuningClose proximityDamped harmonic-oscillator modelsDynamic tuningElectrical tuningPlasmon resonance frequenciesPlasmon resonancesSilver nanoprismsVisible spectraGrapheneGraphiteMetal nanoparticleSilverChemistryEnergy transferLight related phenomenaProceduresSurface plasmon resonanceEnergy TransferGraphiteMetal NanoparticlesOptical PhenomenaSilverSurface Plasmon ResonanceDynamic tuning of plasmon resonance in the visible using grapheneArticle10.1364/OL.41.0012411539-4794
