Nonlinear magneto-gyrotropic photogalvanic effect (2009)

Diehl, Helgi, Shalygin, Vadim, Golub, Leonid, Tarasenko, Sergey, Danilov, Sergey, Belkov, Vassilij, ...

We report on the observation of magnetic-field-induced photocurrent in HgTe/HgCdTe quantum wells of different widths. Both the intrasubband and interband absorption of infrared/terahertz radiation in...

Spin photocurrents and circular photon drag effect in (110)-grown quantum well structures (2007)

Shalygin, Vadim, Diehl, Helgi, Hoffmann, Christoph, Danilov, Sergey, Herrle, Thomas, Tarasenko, Sergey, ...

The study of spin photocurrents in (110)-grown quantum well structures is reported. The investigated effects comprise the circular photogalvanic effect and so far not observed circular photon drag...

Magneto-gyrotropic photogalvanic effect due to inter-subband absorption in (001)-grown GaAs quantum wells (2007)

Diehl, Helgi, Shalygin, V., Danilov, Sergey, Tarasenko, S., Bel'kov, V., Schuh, Dieter, ...

We report on the observation of the magneto-photogalvanic effect (MPGE) due to inter-subband transitions in (001)-oriented GaAs quantum wells. This effect is related to the gyrotropic properties of...
