Hyperfine versus exchange interaction in the spin dynamics of spatially indirect excitons in CsPbI perovskite nanocrystals
Timur S. Shamirzaev, Nataliia E. Kopteva, Dmitry S. Smirnov +7
We study the dynamics of recombination, optical orientation, and optical alignment of excitons in ensembles of CsPbI nanocrystals (NCs), synthesized in a glass matrix. In lar…
Assessing the classicality of photon echo from excitons in lead halide perovskite nanocrystals
George Alkhalil, Hendrik Rose, Artur V. Trifonov +9
Photon echo (PE) spectroscopy is a powerful technique for probing decoherence mechanisms and charge carrier dynamics in semiconductor systems. Beyond traditional coherence measurem…
Millisecond-long electron spin lifetime in CsPbI perovskite nanocrystals revealed by optically detected magnetic resonance
Vasilii V. Belykh, Mikhail M. Glazov, Sergey R. Meliakov +7
Perovskite nanocrystals are a convenient model system for optical spin orientation and manipulation. However, its real potential might be underestimated due to the incomplete knowl…
Quantum beats of exciton-polarons in CsPbI3 perovskite nanocrystals
A. V. Trifonov, M. O. Nestoklon, M. -A. Hollberg +10
Exciton-phonon interactions govern the energy level spectrum and thus the optical response in semiconductors. In this respect, lead-halide perovskite nanocrystals represent a uniqu…
Hyperfine interaction of electrons confined in CsPbI nanocrystals with nuclear spin fluctuations
Sergey R. Meliakov, Evgeny A. Zhukov, Vasilii V. Belykh +6
The coherent spin dynamics of electrons are investigated for CsPbI perovskite nanocrystals in a glass matrix using time-resolved Faraday ellipticity. In nanocrystals with a dia…
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…
