Resonant optical cooling of nuclear spins in case of strong Knight field of photoexcited electrons
Kirill Kavokin
Resonant cooling of the nuclear spin system of a semiconductor by spin-polarized charge carriers under pumping with helicity-modulated polarized light is considered theoretically.…
Optical cooling of nuclear spins in GaAs/(Al,Ga)As quantum wells at subkelvin temperatures: Evidence of the dynamic self-polarization of nuclear spins
M. Kotur, D. Kudlacik, N. E. Kopteva +4
We investigate the dynamic polarization of nuclear spins in a nominally undoped GaAs/AlGaAs quantum well using two complementary experimental approaches: time-res…
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…
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…
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…
