Graphene plasmons: impurities and nonlocal effects
Giovanni Viola, Tobias Wenger, Jari Kinaret +1
This work analyses how impurities and vacancies on the surface of a graphene sample affect its optical conductivity and plasmon excitations. The disorder is analysed in the self-co…
Current-controlled light scattering and asymmetric plasmon propagation in graphene
Tobias Wenger, Giovanni Viola, Jari Kinaret +2
We demonstrate that plasmons in graphene can be manipulated using a DC current. A source-drain current lifts the forward/backward degeneracy of the plasmons, creating two modes wit…
High-sensitivity plasmonic refractive index sensing using graphene
Tobias Wenger, Giovanni Viola, Jari Kinaret +2
We theoretically demonstrate a high-sensitivity, graphene-plasmon based refractive index sensor working in the mid-infrared at room temperature. The bulk figure of merit of our sen…
