Measurement of plasmon dispersion in graphene: tunable graphene plasmonics

ORAL

Abstract

Graphene is an intriguing material for plasmonics. We have measured the transmission spectrum of large area graphene, grown using chemical vapor deposition, using Fourier transform infrared spectroscopy. By varying the Fermi level of graphene, we are able to explore the energy dispersion of plasmons in graphene. Our result lays the foundation for tunable plasmonic devices based on graphene.
