Graphene Electrodynamics in the presence of the Extrinsic Spin Hall Effect
Chunli Huang, Yidong Chong, Giovanni Vignale +1
We extend the electrodynamics of two dimensional electron gases to account for the extrinsic spin Hall effect (SHE). The theory is applied to doped graphene decorated with a random…
Extrinsic Spin Hall Effect from Anisotropic Rashba Spin-Orbit Coupling in Graphene
H-Y. Yang, Chunli Huang, Hector Ochoa +1
We study the effect of anisotropy of the Rashba coupling on the extrinsic spin Hall effect due to spin-orbit active adatoms on graphene. In addition to the intrinsic spin-orbit cou…
Absence of Perfect Conductance Quantization of Helical-edge Transport in Graphene under a Strong, Tilted Magnetic Field
Chunli Huang, Miguel. A. Cazalilla
In a recent experiment, Young et al. [Nature {\bf 505}, 528 (2014)] observed a metal to insulator transition as well as transport through helical edge states in monolayer graphene…
Electron-spin to Phonon Coupling in Graphene Decorated with Heavy Adatoms
Jhih-Shih You, Daw-Wei Wang, Miguel A. Cazalilla
The naturally weak spin-orbit coupling in Graphene can be largely enhanced by adatom deposition (e.g. Weeks et al. Phys. Rev. X 1, 021001 (2011)). However, the dynamics of the adat…
