Anomalously strong pinning of the filling factor nu=2 in epitaxial graphene
T. J. B. M. Janssen, A. Tzalenchuk, R. Yakimova +4
We explore the robust quantization of the Hall resistance in epitaxial graphene grown on Si-terminated SiC. Uniquely to this system, the dominance of quantum over classical capacit…
Circular ac Hall Effect
J. Karch, P. Olbrich, M. Schmalzbauer +13
We report the observation of the circular ac Hall effect where the current is solely driven by the crossed ac electric and magnetic fields of circularly polarized radiation. Illumi…
Photon helicity driven electric currents in graphene
J. Karch, P. Olbrich, M. Schmalzbauer +8
We report on the observation of photon helicity driven currents in graphene. The directed net electric current is generated in single layer graphene by circularly polarized teraher…
