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…
Spin Dynamics and Relaxation in Graphene Dictated by Electron-hole Puddles
Dinh Van Tuan, Frank Ortmann, Aron W. Cummings +2
The understanding of spin dynamics and relaxation mechanisms in clean graphene and the upper time and length scales on which spin devices can operate are prerequisites to realizing…
Spin Transport in Hydrogenated Graphene
David Soriano, Dinh Van Tuan, Simon M. -M. Dubois +7
In this review we discuss the multifaceted problem of spin transport in hydrogenated graphene from a theoretical perspective. The current experimental findings suggest that hydroge…
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…
