Unconventional Features in the Quantum Hall Regime of Disordered Graphene: Percolating Impurity States and Hall Conductance Quantization
Nicolas Leconte, Frank Ortmann, Alessandro Cresti +1
We report on the formation of critical states in disordered graphene, at the origin of variable and unconventional transport properties in the quantum Hall regime, such as a zero-e…
Velocity renormalization and Dirac cone multiplication in graphene superlattices with various barrier edge geometries
Albert de Jamblinne de Meux, Nicolas Leconte, Jean-Christophe Charlier +1
The electronic properties of one-dimensional graphene superlattices strongly depend on the atomic size and orientation of the 1D external periodic potential. Using a tight-binding…
Efficient Linear Scaling Approach for Computing the Kubo Hall Conductivity
Frank Ortmann, Nicolas Leconte, Stephan Roche
We report an order-N approach to compute the Kubo Hall conductivity for disorderd two-dimensional systems reaching tens of millions of orbitals, and realistic values of the applied…
