Millisecond spin coherence of electrons in semiconducting perovskites revealed by spin mode locking
Sergey R. Meliakov, Evgeny A. Zhukov, Vasilii V. Belykh +4
Long spin coherence times of carriers are essential for implementing quantum technologies using semiconductor devices for which, however, a possible obstacle is spin relaxation. Fo…
Spin-dependent Raman and Brillouin light scattering on excitons in CsPbBr perovskite crystals
Ina V. Kalitukha, Victor F. Sapega, Dmitri R. Yakovlev +5
The spin properties of excitons and charge carriers in CsPbBr lead halide perovskite crystals are investigated by spin-dependent light scattering in magnetic fields up to 10 T.…
Magnetoluminescence of ZnMnSe/BeMnTe heterostructures with type-II band alignment at millikelvin temperatures
Dennis Kudlacik, Linda Kersting, Nataliia E. Kopteva +3
The magneto-optical properties of a ZnMnSe/BeMnTe diluted magnetic semiconductor heterostructure with type-II band alignment are investigated a…
Polarization- and time-resolved nonlinear multi-photon spectroscopy for confocal microscopy of semiconductor nanostructures
Nikita V. Siverin, Andreas Farenbruch, Dmitri R. Yakovlev +4
We present a versatile confocal microscopy setup for optical second harmonic generation (SHG) and multi-photon spectroscopy that enables polarization-resolved studies of semiconduc…
Interaction between Rydberg Excitons in Cuprous Oxide Revealed through Second Harmonic Generation
Dirk Semkat, Heinrich Stolz, Peter Grünwald +5
We report experimental and theoretical investigations of interacting excitons of the yellow series in cuprous oxide (CuO) with principal quantum numbers up to by means of…
Confined acoustic phonons in CsPbI3 nanocrystals explored by resonant Raman scattering on excitons
Carolin Harkort, Ina V. Kalitukha, Nataliia E. Kopteva +8
Optical properties of the lead halide perovskites nanocrystals are controlled by confined excitons and rich spectrum of confined acoustic and optical phonons. We study experimental…
