Optical Properties of Strained Graphene
Vitor M. Pereira, R. M. Ribeiro, N. M. R. Peres +1
The optical conductivity of graphene strained uniaxially is studied within the Kubo-Greenwood formalism. Focusing on inter-band absorption, we analyze and quantify the breakdown of…
Mechanism for graphene-based optoelectronic switches by tuning surface plasmon-polaritons in monolayer graphene
Yu. V. Bludov, M. I. Vasilevskiy, N. M. R. Peres
It is shown that one can explore the optical conductivity of graphene, together with the ability of controlling its electronic density by an applied gate voltage, in order to achie…
Transport properties of graphene with one-dimensional charge defects
A. Ferreira, Xiangfan Xu, Chang-Lin Tan +5
We study the effect of extended charge defects in electronic transport properties of graphene. Extended defects are ubiquitous in chemically and epitaxially grown graphene samples…
Colloquium: The transport properties of graphene: An introduction
N. M. R. Peres
An introduction to the transport properties of graphene combining experimental results and theoretical analysis is presented. In the theoretical description simple intuitive models…
Bilayer graphene: gap tunability and edge properties
Eduardo V. Castro, N. M. R. Peres, J. M. B. Lopes dos Santos +2
Bilayer graphene -- two coupled single graphene layers stacked as in graphite -- provides the only known semiconductor with a gap that can be tuned externally through electric fiel…
Excitonic effects in the optical conductivity of gated graphene
N. M. R. Peres, R. M. Ribeiro, A. H. Castro Neto
We study the effect of electron-electron interactions in the optical conductivity of graphene under applied bias and derive a generalization of Elliot's formula, commonly used for…
