Circular polarization immunity of the cyclotron resonance photoconductivity in two-dimensional electron systems
Erwin Mönch, Philipp Euringer, Georg-Maximilian Hüttner +7
Studying the cyclotron resonance (CR)-induced photoconductivity in GaAs and HgTe two-dimensional electron structures, we observed an anomalous photoresponse for the CR-inactive geo…
Exciton fine structure splitting and linearly polarized emission in strained transition-metal dichalcogenide monolayers
M. M. Glazov, Florian Dirnberger, Vinod M. Menon +5
We study theoretically effects of an anisotropic elastic strain on the exciton energy spectrum fine structure and optical selection rules in atom-thin crystals based on transition-…
Wurtzite quantum wires with strong spatial confinement: polarization anisotropies in single wire spectroscopy
Viola Zeller, Nadine Mundigl, Paulo E. Faria Junior +3
We report GaAs/AlGaAs nanowires in the one-dimensional (1D) quantum limit. The ultrathin wurtzite GaAs cores between 20-40\,nm induce large confinement energies of several tens of…
