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.…
Spin dynamics of excitons and carriers in mixed-cation MAFAPbI perovskite crystals: alloy fluctuations probed by optical orientation
B. F. Gribakin, N. E. Kopteva, D. R. Yakovlev +5
Optical spin orientation measured by time-resolved photoluminescence provides a powerful tool to probe the spin dynamics of excitons and charge carriers in perovskite semiconductor…
Magnetic switching of exciton lifetime in CrSBr
Ina V. Kalitukha, Ilya A. Akimov, Mikhail O. Nestoklon +13
Exciton dynamics in layered magnetic semiconductors provide a sensitive probe of the interplay between spin order and light-matter interaction. Here, we study thin CrSBr layers usi…
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…
Effect of crystal symmetry of lead halide perovskites on the optical orientation of excitons
Nataliia E. Kopteva, Dmitri R. Yakovlev, Eyüp Yalcin +8
The great variety of lead halide perovskite semiconductors represents an outstanding platform for studying crystal symmetry effects on the spin-dependent properties. Access to them…
