Electrostatics of metal-graphene interfaces: sharp p-n junctions for electron-optical applications
Ferney A. Chaves, David Jimenez, Jaime E. Santos +2
Creation of sharp lateral p-n junctions in graphene devices, with transition widths well below the Fermi wavelength of graphene charge carriers, is vital to study and exploit these…
Renormalization of nanoparticle polarizability in the vicinity of a graphene-covered interface
Jaime E. Santos, M. I. Vasilevskiy, N. M. R. Peres +2
We study the electromagnetic properties of a metamaterial consisting of polarizable (nano)particles and a single graphene sheet placed at the interface between two dielectrics. We…
Optical bistability of graphene in the terahertz range
N. M. R. Peres, Yu. V. Bludov, Jaime E. Santos +2
We use an exact solution of the relaxation-time Boltzmann equation in a uniform AC electric field to describe the nonlinear optical response of graphene in the terahertz (THz). The…
Strong light-matter interaction in systems described by a modified Dirac equation
N. M. R. Peres, Jaime E. Santos
The bulk states of some materials, such as topological insulators, are described by a modified Dirac equation. Such systems may have trivial and non-trivial phases. In this paper,…
Thermodynamics of a Potts-like model for a reconstructed zigzag edge in graphene nanoribbons
J. N. B. Rodrigues, P. A. D. Gonçalves, Jaime E. Santos +1
We construct a three-color Potts-like model for the graphene zigzag edge reconstructed with Stone-Wales carbon rings, in order to study its thermal equilibrium properties. We consi…
