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…

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…

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…
