A study of the nonlinear optical response of the plain graphene and gapped graphene monolayers beyond the Dirac approximation
G. B. Ventura, D. J. Passos, J. M. Viana Parente Lopes +1
In this work, we present numerical results for the second and third order conductivities of the plain graphene and gapped graphene monolayers associated with the second and third h…
Scattering by linear defects in graphene: a continuum approach
J. N. B. Rodrigues, N. M. R. Peres, J. M. B. Lopes dos Santos
We study the low-energy electronic transport across periodic extended defects in graphene. In the continuum low-energy limit, such defects act as infinitesimally thin stripes separ…
Coulomb Drag and High Resistivity Behavior in Double Layer Graphene
N. M. R. Peres, J. M. B. Lopes dos Santos, A. H. Castro Neto
We show that Coulomb drag in ultra-clean graphene double layers can be used for controlling the on/off ratio for current flow by tunning the external gate voltage. Hence, although…
Dirac electrons in graphene-based quantum wires and quantum dots
N. M. R. Peres, J. N. B. Rodrigues, T. Stauber +1
In this paper we analyse the electronic properties of Dirac electrons in finite-size ribbons and in circular and hexagonal quantum dots made of graphene.
Localized States at Zigzag Edges of Multilayer Graphene and Graphite Steps
Eduardo V. Castro, N. M. R. Peres, J. M. B. Lopes dos Santos
We report the existence of zero energy surface states localized at zigzag edges of -layer graphene. Working within the tight-binding approximation, and using the simplest neares…
Gaped graphene bilayer: disorder and magnetic field effects
Eduardo V. Castro, N. M. R. Peres, J. M. B. Lopes dos Santos
Double layer graphene is a gapless semiconductor which develops a finite gap when the layers are placed at different electrostatic potentials. We study, within the tight-biding app…
