Edge currents driven by terahertz radiation in graphene in quantum Hall regime
H. Plank, M. V. Durnev, S. Candussio +9
We observe that the illumination of unbiased graphene in the quantum Hall regime with polarized terahertz laser radiation results in a direct edge current. This photocurrent is cau…

Infrared/Terahertz Spectra of the Photogalvanic Effect in (Bi,Sb)Te based Three Dimensional Topological Insulators
H. Plank, J. Pernul, S. Gebert +9
We report on the systematic study of infrared/terahertz spectra of photocurrents in (Bi,Sb)Te based three dimensional topological insulators. We demonstrate that in a wide range of…
