TL;DR: It is shown that the opacity of suspended graphene is defined solely by the fine structure constant, a = e2/hc � 1/137 (where c is the speed of light), the parameter that describes coupling between light and relativistic electrons and that is traditionally associated with quantum electrodynamics rather than materials science.
Journal ArticleDOI
Dynamical polarization of graphene at finite doping
TL;DR: In this paper, the polarization of graphene is calculated exactly within the random phase approximation for arbitrary frequency, wavevector and doping, and the dynamical polarization for low q and arbitrary ω is employed to calculate the dispersion relation and the decay rate of plasmons and acoustic phonons.
Journal ArticleDOI
Optical conductivity of graphene in the visible region of the spectrum
TL;DR: In this paper, the optical conductivity of graphene has been computed beyond the usual Dirac-cone approximation, giving results that are valid in the visible region of the conductivity spectrum.
Journal ArticleDOI
Electronic transport in graphene: A semiclassical approach including midgap states
TL;DR: In this article, the authors calculate the conductivity as a function of the carrier density and propose an additional scattering mechanism involving midgap states, which leads to a similar $k$ dependence of the relaxation time as charged impurities.
Journal ArticleDOI
Plasmonics in Dirac systems: from graphene to topological insulators
TL;DR: Deep intrinsic plasmon excitation of single and bilayer graphene via hydrodynamic equations and the random phase approximation is discussed and a comprehensive introduction to the standard models and techniques is given.
