Recently, graphene has received a great deal of attention both experimentally and theoretically because of its unusually device-friendly material properties, including high mobility, high electron density, and long-carrier mean-free-path, etc. It has also been shown that graphene-based chemical sensors are capable of detecting minute concentrations (1 part per billion) of various active gases due...
Taking account of both the electron-impurity and electron-phonon scatterings, the anomalous Hall effect in two dimensional electron systems is investigated by means of a kinetic equation approach. The spin-orbit coupling directly induced by an external driving electric field and the extrinsic spin-orbit coupling (associated with electron-impurity and electron-phonon scatterings) are included. The...
