7 p, 2.2 MB Nonlocal Spin Dynamics in the Crossover from Diffusive to Ballistic Transport / Vila Tusell, Marc (Institut Català de Nanociència i Nanotecnologia) ; Garcia, José H.

(Université Grenoble Alpes) ; Waintal, Xavier (Université Grenoble Alpes) ; Roche, Stephan (Institut Català de Nanociència i Nanotecnologia)
Improved fabrication techniques have enabled the possibility of ballistic transport and unprecedented spin manipulation in ultraclean graphene devices. Spin transport in graphene is typically probed in a nonlocal spin valve and is analyzed using spin diffusion theory, but this theory is not necessarily applicable when charge transport becomes ballistic or when the spin diffusion length is exceptionally long.

Since its discovery, graphene has been a promising material for spintronics: its low spin-orbit coupling, negligible hyperfine interaction, and high electron mobility are obvious advantages for transporting spin information over long distances. [...]

Graphene is an excellent material for long-distance spin transport but allows little spin manipulation. Transition-metal dichalcogenides imprint their strong spin-orbit coupling into graphene via the proximity effect, and it has been predicted that efficient spin-to-charge conversion due to spin Hall and Rashba-Edelstein effects could be achieved.

(Institut Català de Nanociència i Nanotecnologia) ; Reily Rocha, Alexandre (Universidade Estadual Paulista (Brasil)) ; Rappoport, Tatiana G. (Universidade Federal Do Rio de Janeiro)
We consider an effective model for graphene with interface-induced spin-orbit coupling and calculate the quantum Hall effect in the low-energy limit. We perform a systematic analysis of the contribution of the different terms of the effective Hamiltonian to the quantum Hall effect (QHE). [...]

Modern electronic structure calculations are predominantly implemented within the super cell representation in which unit cells are periodically arranged in space. Even in the case of non-crystalline materials, defect-embedded unit cells are commonly used to describe doped structures. [...]

The discovery of the integer quantum Hall effect in the early eighties of the last century, with highly precise quantization values for the Hall conductance in multiples of e2/h, has been the first fascinating manifestation of the topological state of matter driven by magnetic field and disorder, and related to the formation of non-dissipative current flow.
