Two-dimensional carbon, or graphene, is a semimetal that presents unusual low-energy electronic excitations described in terms of Dirac fermions. We analyze in a self-consistent way the effects of localized (impurities or vacancies) and extended (edges or grain boundaries) defects on the electronic and transport properties of graphene. On the one hand, point defects induce a finite elastic lifetime at low energies with the enhancement of the electronic density of states close to the Fermi level… 

Electronic properties of graphene with point defects

This article attempts a point-by-point review of the electron spectrum of graphene containing defects (adsorbed atoms, substitutional atoms, vacancies) that can be adequately described within the

Effect of impurities in high-symmetry lattice positions on the local density of states and conductivity of graphene

Motivated by quantum chemistry calculations, showing that molecular adsorption in graphene takes place on preferential sites of the honeycomb lattice, we study the effect of an isolated impurity on

Electronic properties of graphene with point defects (Review Article)

This review is an attempt to consistently examine the electronic spectrum of graphene containing defects (such as adsorbed atoms, substitutional atoms, vacancies) that can be adequately described

Electronic properties of graphene multilayers.

It is shown that the quasiparticle decay rate has a minimum as a function of energy, there is a universal minimum value for the in-plane conductivity of order e(2)/h per plane and, unexpectedly, the c-axis conductivity is enhanced by disorder at low doping, leading to an enormous conductivity anisotropy at low temperatures.


Graphene, a single atom thick plane of graphite, is a novel two-dimensional electron system in which the low-energy electrons behave as massless chiral Dirac fermions. This thesis explores the

Electronic signatures of topological disorder in amorphous graphene

The authors employ realistic structural models, and find that the electronic states around Fermi level are highly localised around odd-membered rings, and predict an scanning tunnelling microscopic image for the amorphous surface.

Electronic properties of two-dimensional carbon systems

Properties of graphene-based nanoelectronic devices are found to be limited by disorder, e.g., vacancies, impurities and ripples on the surface. We investigate the specific effect of defects

Electronic transport in two-dimensional graphene

We provide a broad review of fundamental electronic properties of two-dimensional graphene with the emphasis on density and temperature dependent carrier transport in doped or gated graphene

It is shown that there is a phase transition between the semimetal and metallic phases followed by a localization transition and the symmetry breaking associated with this transition is related to the nonsymmorphic character of the space group.

Experimental observation of the quantum Hall effect and Berry's phase in graphene

An experimental investigation of magneto-transport in a high-mobility single layer of graphene observes an unusual half-integer quantum Hall effect for both electron and hole carriers in graphene.

Π à la Node: Disordered d-Wave Superconductors in Two Dimensions for the Random Masses

We review work on the problem of disorder in the 2D d-wave superconducting state, and show that the symmetries of the normal state and the disorder distribution are vital for understanding the

Quantized Hall conductance, current carrying edge states, and the existence of extended states in a two-dimensional disordered potential

When a conducting layer is placed in a strong perpendicular magnetic field, there exist current-carrying electron states which are localized within approximately a cyclotron radius of the sample

Disorder induced localized States in graphene.

It is shown that vacancies induce the formation of localized states in the half-filled honeycomb lattice when particle-hole symmetry is broken, and localized states become resonances close to the Fermi level.

Quantum Transport in Two-Dimensional Graphite System

In a self-consistent Born approximation, the density of states and the conductivity are calculated in a two-dimensional graphite sheet in magnetic fields. Two different cases of scatterers are
