Paper Abstract

We propose the exploitation of plasmons in graphene nanoislands as a promising platform for sensing through surface-enhanced infrared absorption and Raman scattering. Our calculations indicate that the large electrical tunability of graphene enables the identification of molecular resonances by recording broadband absorption or inelastic scattering, replacing wavelength-resolved light collection by a signal integrated over photon energy as a function of the graphene doping level. Our results pave the way for the development of novel cost-effective sensors capable of identifying spectral signatures of molecules without using spectrometers and laser sources.
