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…
Photogalvanic effects due to quantum interference in optical transitions demonstrated by terahertz radiation absorption in Si-MOSFETs
P. Olbrich, S. A. Tarasenko, C. Reitmaier +4
We report on the observation of the circular (helicity-dependent) and linear photogalvanic effects in Si-MOSFETs with inversion channels. The developed microscopic theory demonstra…
Quantum ratchet effects induced by terahertz radiation in GaN-based two-dimensional structures
W. Weber, L. E. Golub, S. N. Danilov +10
Photogalvanic effects are observed and investigated in wurtzite (0001)-oriented GaN/AlGaN low-dimensional structures excited by terahertz radiation. The structures are shown to rep…
Magneto-gyrotropic effects in semiconductor quantum wells (review)
V. V. Bel'kov, S. D. Ganichev
Magneto-gyrotropic photogalvanic effects in quantum wells are reviewed. We discuss experimental data, results of phenomenological analysis and microscopic models of these effects.…
