Circular and Linear Photogalvanic Effects in Type-II GaSb/InAs Quantum Well Structures in the Inverted Regime

H. Plank, S. A. Tarasenko, T. Hummel +5

We report on the observation of photogalvanic effects induced by terahertz radiation in type-II GaSb/InAs quantum wells with inverted band order. Photocurrents are excited at obliq…

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…
