Graphene plasmons in the presence of adatoms

open access: yesNew Journal of Physics, 2017
We theoretically investigate graphene plasmons in the presence of a low density of adatoms on the graphene surface. The adatoms can significantly modify the conductivity and plasmonic properties of graphene and may produce a level splitting with the ...

Graphene plasmonics: physics and potential applications

open access: yesNanophotonics, 2016
Plasmon in graphene possesses many unique properties. It originates from the collective motion of massless Dirac fermions, and the carrier density dependence is distinctively different from conventional plasmons.

Plasmons in electrostatically doped graphene [PDF]

open access: yes, 2012
Graphene has raised high expectations as a low-loss plasmonic material in which the plasmon properties can be controlled via electrostatic doping. Here, we analyze realistic configurations, which produce inhomogeneous doping, in contrast to what has been

Experimental demonstration of graphene plasmons working close to the near-infrared window [PDF]

open access: yes, 2016
Due to strong mode-confinement, long propagation-distance, and unique tunability, graphene plasmons have been widely explored in the mid-infrared and terahertz windows.

Graphene as a source of entangled plasmons

open access: yesPhysical Review Research, 2022
We analyze nonlinear optics schemes for generating pairs of quantum entangled plasmons in the terahertz-infrared range in graphene. We predict that high plasmonic field concentration and strong optical nonlinearity of monolayer graphene enables pair ...

Enhanced graphene nonlinear response through geometrical plasmon focusing [PDF]

open access: yes, 2018
We propose a simple approach to couple light into graphene plasmons and focus these excitations at focal spots of a size determined by the plasmon wavelength, thus producing high optical field enhancement that boosts the nonlinear response of the ...

Plasmons driven by single electrons in graphene nanoislands

open access: yesNanophotonics, 2013
Plasmons produce large confinement and enhancement of light that enable applications as varied as cancer therapy and catalysis. Adding to these appealing properties, graphene has emerged as a robust, electrically tunable material exhibiting plasmons that

Microscopic analysis of gain spectrum of surface plasmons in graphene

open access: yesResults in Physics, 2016
In this paper, microscopic interactions of surface plasmons and carriers in the graphene layer are investigated and based on the second quantization formalism, rate equations of surface plasmons are presented. Plasmonic matrix element for surface plasmon-
