Electron confinement induced by diluted hydrogen-like ad-atoms in graphene ribbons
(2015)
We report the electronic properties of two-dimensional systems made of graphene nanoribbons, which are patterned with ad-atoms in two separated regions. Due to the extra electronic confinement induced by the presence of ...
Direct Observation of Single Layer Graphene Oxide Reduction through Spatially Resolved, Single Sheet Absorption/Emission Microscopy
(American Chemical Society, 2014-05)
Laser reduction of graphene oxide (GO) offers unique opportunities for the rapid, nonchemical production of graphene. By tuning relevant reduction parameters, the band gap and conductivity of reduced GO can be precisely ...
Floquet chiral edge states in graphene
(American Physical Society, 2014-03-15)
We report on the emergence of laser-induced chiral edge states in graphene ribbons. Insights on the nature of these Floquet states is provided by an analytical solution which is complemented with numerical simulations of ...
Induced Brehemstrahlung by light in graphene
(2018)
We study the generation of an electromagnetic current in monolayer graphene immersedin a weak perpendicular magnetic eld and radiated with linearly polarized monochromatic light.Such a current emits Brehemstrahlung radiation ...
Enhancement of Fano-resonance response in bilayer graphene single and double barriers induced by bandgap opening
(Elsevier, 2020-05-10)
Fano resonances in bilayer graphene arise due to the coupling between extended and discrete electrons states, and represent an exotic phenomenon in graphene akin to Klein and anti-Klein tunneling, atomic collapse and ...
