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…
Scaling Properties of Polycrystalline Graphene: A Review
Andreas Isacsson, Aron W. Cummings, Luciano Colombo +3
We present an overview of the electrical, mechanical, and thermal properties of polycrystalline graphene. Most global properties of this material, such as the charge mobility, ther…
Optical signatures of nonlocal plasmons in graphene
Tobias Wenger, Giovanni Viola, Philippe Tassin +2
We theoretically investigate under which conditions nonlocal plasmon response in monolayer graphene can be detected. To this purpose, we study optical scattering off graphene plasm…
Nonlinear Damping in Graphene Resonators
Alexander Croy, Daniel Midtvedt, Andreas Isacsson +1
Based on a continuum mechanical model for single-layer graphene we propose and analyze a microscopic mechanism for dissipation in nanoelectromechanical graphene resonators. We find…
