Resonant cooling of nuclear spins by optically-oriented holes in MAPbI perovskite crystals
Mladen Kotur, Dmitri R. Yakovlev, Nataliia E. Kopteva +3
Resonant cooling of nuclear spins by photogenerated spin-oriented holes is demonstrated for MAPbI perovskite crystals. It is evidenced by Hanle-effect measurements under helici…
Hyperfine interaction of electrons and holes with nuclei probed by optical orientation in MAPbI perovskite crystals
Mladen Kotur, Nataliia E. Kopteva, Dmitri R. Yakovlev +3
Optical orientation of electron and hole spins by circularly polarized light is investigated for MAPbI single crystals. The Hanle and polarization recovery effects measured in…
Dynamic polarization of nuclear spins by optically-oriented electrons and holes in lead halide perovskite semiconductors
Mladen Kotur, Pavel S. Bazhin, Kirill V. Kavokin +4
A theory of dynamic polarization of the nuclear spin system via optically-oriented charge carriers in lead halide perovskites is developed and compared with the experiments perform…
Optical orientation of excitons and charged carriers in MAPbI perovskite single crystals in the orthorhombic phase
Nataliia E. Kopteva, Dmitri R. Yakovlev, Eyüp Yalcin +6
Optical orientation of exciton and carrier spins by circularly polarized light is the basic phenomenon in the spin physics of semiconductors. Here, we investigate spin orientation…
Optical spin orientation of localized electrons and holes interacting with nuclei in an FACsPbIBr perovskite crystal
Dennis Kudlacik, Nataliia E. Kopteva, Mladen Kotur +8
Optical orientation of carrier spins by circularly polarized light is the basic concept and tool of spin physics in semiconductors. We study the optical orientation of electrons an…
Nuclear spin relaxation mediated by donor-bound and free electrons in wide CdTe quantum wells
Boris F. Gribakin, Valentina M. Litvyak, Mladen Kotur +4
The nuclear spin systems in CdTe/(Cd,Zn)Te and CdTe/(Cd,Mg)Te quantum wells (QW) are studied using a multistage technique combining optical pumping and Hanle effect-based detection…
