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…
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…
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…
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…
Light-driven modulation of proximity-enhanced functionalities in hybrid nano-scale systems
Mattia Benini, Umut Parlak, Sophie Bork +11
Advancing quantum information and communication technology (qICT) requires smaller and faster components with actively controllable functionalities. This work presents a novel stra…
Resonant spin amplification and accumulation in MAPbI single crystals
Erik Kirstein, Dmitri R. Yakovlev, Evgeny A. Zhukov +4
Quantum technologic and spintronic applications require reliable semiconducting materials that enable a significant, long-living spin polarization of electronic excitations and off…
