Fast detector of the ellipticity of infrared and terahertz radiation based on HgTe quantum well structures
S. N. Danilov, B. Wittmann, P. Olbrich +12
We report a fast, room temperature detection scheme for the polarization ellipticity of laser radiation, with a bandwidth that stretches from the infrared to the terahertz range. T…
Symmetry and spin dephasing in (110)-grown quantum wells
V. V. Bel'kov, P. Olbrich, S. A. Tarasenko +7
Symmetry and spin dephasing of in (110)-grown GaAs quantum wells (QWs) are investigated applying magnetic field induced photogalvanic effect (MPGE) and time-resolved Kerr rotation.…
Magneto-gyrotropic photogalvanic effects in GaN/AlGaN two-dimensional systems
W. Weber, S. Seidl, S. N. Danilov +8
The magneto-gyrotropic photogalvanic and spin-galvanic effects are observed in (0001)-oriented GaN/AlGaN heterojunctions excited by terahertz radiation. We show that free-carrier a…
All-electric detectors of the polarization state of terahertz laser radiation (extended version)
S. D. Ganichev, W. Weber, J. Kiermaier +7
Two types of room temperature detectors of terahertz laser radiation have been developed which allow in an all-electric manner to determine the plane of polarization of linearly po…
Cyclotron resonance photoconductivity of a two-dimensional electron gas in HgTe quantum wells
Ze-Don Kvon, Sergey N. Danilov, Nikolay N. Mikhailov +3
Far-infrared cyclotron resonance photoconductivity (CRP) is investigated in HgTe quantum wells (QWs) of various widths grown on (013) oriented GaAs substrates. It is shown that CRP…
Photogalvanic effects in HgTe quantum wells
B. Wittmann, R. Ravash, H. Diehl +8
We report on the observation of the terahertz radiation induced circular (CPGE) and linear (LPGE) photogalvanic effects in HgTe quantum wells. The current response is well describe…
