Cyclotron Resonance Assisted Photocurrents in Surface States of a 3D Topological Insulator Based on a Strained High Mobility HgTe Film
K. -M. Dantscher, D. A. Kozlov, P. Olbrich +12
We report on the observation of cyclotron resonance induced photocurrents, excited by continuous wave terahertz radiation, in a 3D topological insulator (TI) based on an 80 nm stra…
Spin-polarized electric currents in diluted magnetic semiconductor heterostructures induced by terahertz and microwave radiation
P. Olbrich, C. Zoth, P. Lutz +11
We report on the study of spin-polarized electric currents in diluted magnetic semiconductor (DMS) quantum wells subjected to an in-plane external magnetic field and illuminated by…
Interplay of spin and orbital magnetogyrotropic photogalvanic effects in InSb/AlInSb quantum well structures
S. Stachel, P. Olbrich, C. Zoth +9
We report on the observation of linear and circular magnetogyrotropic photogalvanic effects in InSb/AlInSb quantum well structures. We show that intraband (Drude-like) absorption o…
Spin polarized electric currents in semiconductor heterostructures induced by microwave radiation
C. Drexler, V. V. Bel'kov, B. Ashkinadze +10
We report on microwave (mw) radiation induced electric currents in (Cd,Mn)Te/(Cd,Mg)Te and InAs/(In,Ga)As quantum wells subjected to an external in-plane magnetic field. The curren…
