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…
Layer-dependent Landé -factors of electrons, holes, and excitons in two-dimensional Ruddlesden-Popper lead halide perovskites
Nataliia E. Kopteva, Dmitri R. Yakovlev, Mikhail O. Nestoklon +9
Two-dimensional Ruddlesden-Popper lead halide perovskites provide a valuable platform for tailoring charge and spin properties through quantum confinement and reduced symmetry. Whi…

The unique combination of outstanding optical quality and attractive spin properties opens new avenues for optical spin control in hybrid organic-inorganic perovskite semiconductor…
Scaling laws of electron and hole spin relaxation in indirect band gap (In,Al)As/AlAs quantum dots
T. S. Shamirzaev, D. R. Yakovlev, D. S. Smirnov +2
We investigate the electron and heavy hole spin dynamics as a function of magnetic field in ensembles of indirect band gap (In,Al)As/AlAs quantum dots (QDs) with type-I band alignm…
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…
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…
