Magneto-photoelectric effect in graphene via tailored potential landscapes — •Friedemann Queisser1, Joris Josiek1,2, Stephan Winnerl1, and Ralf Schützhold1,2 — 1Helmholtz-Zentrum Dresden-Rossendorf, Bautzner Landstraße 400, 01328 Dresden, Germany — 2Institut für Theoretische Physik, Technische Universität Dresden, 01062 Dresden, Germany
We consider the propagation of charge carriers in planar graphene under the combined influence of a constant transversal magnetic field and an in-plane varying electric potential. By suitably designing the potential landscape, we may effectively steer charge carriers generated by photo-excitation, for example, in order to achieve an efficient charge separation. These finding may pave the way for transport schemes or photoelectric/photovoltaic applications. Funding by the DFG through the SFB 1242 is gratefully acknowledged.
