Structural phase transitions in double perovskite crystals studied by Brillouin light scattering
D. O. Horiachyi, M. O. Nestoklon, I. A. Akimov +5
Inorganic lead-free double perovskites represent particular interest as non-toxic and stable material platform for optoelectronic applications. Here, we employ Brillouin light scat…
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…
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…
