Symmetry breaking and circular photogalvanic effect in epitaxial CdHgTe films
S. Hubmann, G. V. Budkin, M. Otteneder +13
We report on the observation of symmetry breaking and the circular photogalvanic effect in CdHgTe alloys. We demonstrate that irradiation of bulk epitaxial films with c…
Excitation and coherent control of spin qudit modes with sub-MHz spectral resolution
V. A. Soltamov, C. Kasper, A. V. Poshakinskiy +7
Quantum bit or qubit is a two-level system, which builds the foundation for quantum computation, simulation, communication and sensing. Quantum states of higher dimension, i.e., qu…
Persistent Spin Helix Manipulation by Optical Doping of a CdTe Quantum Well
F. Passmann, S. Anghel, T. Tischler +6
Time-resolved Kerr-rotation microscopy explores the influence of optical doping on the persistent spin helix in a [001]-grown CdTe quantum well at cryogenic temperatures. Electron…
Gate-Control of Anisotropic Spin Transport and Spin Helix Dynamics in a Modulation-Doped GaAs Quantum Well
S. Anghel, F. Passmann, A. Singh +10
Electron spin transport and dynamics are investigated in a single, high-mobility, modulation-doped, GaAs quantum well using ultrafast two-color Kerr-rotation micro-spectroscopy, su…
Photogalvanic probing of helical edge channels in 2D HgTe topological insulators
K. -M. Dantscher, D. A. Kozlov, M. T. Scherr +10
We report on the observation of a circular photogalvanic current excited by terahertz (THz) laser radiation in helical edge channels of HgTe-based 2D topological insulators (TIs).…
Spin splitting of electron states in lattice-mismatched (110)-oriented quantum wells
M. O. Nestoklon, S. A. Tarasenko, R. Benchamekh +1
We show that for lattice-mismatched zinc-blende-type (110)-grown quantum wells a significant contribution to the zero-magnetic-field spin splitting of electron subbands comes from…
