Photogalvanic probing of helical edge channels in 2D HgTe topological insulators
K. -M. Dantscher, D. A. Kozlov, M. T. Scherr +10
We report on the observation of a circular photogalvanic current excited by terahertz (THz) laser radiation in helical edge channels of HgTe-based 2D topological insulators (TIs).…

Opto-Electronic Characterization of Three Dimensional Topological Insulators
Helene Plank, Sergey N. Danilov, Vasily V. Bel'kov +6
We demonstrate that the terahertz/infrared radiation induced photogalvanic effect, which is sensitive to the surface symmetry and scattering details, can be applied to study the hi…
