Optical conductivity of ABA stacked graphene trilayer: mid-IR resonance due to band nesting
Zeinab Rashidian, Yuliy V. Bludov, Ricardo M. Ribeiro +2
The band structure and the optical conductivity of an ABA (Bernal-type) stacked graphene trilayer are calculated. It is shown that, under appropriate doping, a strong resonant peak…
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…
Strained graphene: tight-binding and density functional calculations
R. M. Ribeiro, Vitor M. Pereira, N. M. R. Peres +2
We determine the band structure of graphene under strain using density functional calculations. The ab-initio band strucure is then used to extract the best fit to the tight-bindin…
Scanning Tunneling Microscopy currents on locally disordered graphene
N. M. R. Peres, Shan-Wen Tsai, J. E. Santos +1
We study the local density of states at and around a substituting impurity and use these results to compute current versus bias characteristic curves of Scanning Tunneling Microsco…
Distortion of the perfect lattice structure in bilayer graphene
Vitor M. Pereira, R. M. Ribeiro, N. M. R. Peres +1
We consider the instability of bilayer graphene with respect to a distorted configuration in the same spirit as the model introduced by Su, Schrieffer and Heeger. By computing the…
Inducing energy gaps in graphene monolayer and bilayer
R. M. Ribeiro, N. M. R. Peres, J. Coutinho +1
In this paper we propose a mechanism for the induction of energy gaps in the spectrum of graphene and its bilayer, when both these materials are covered with water and ammonia mole…
