Spin dynamics of excitons and carriers in mixed-cation MA $_{x}$ FA $_{1 - x}$ PbI $_{3}$ 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…

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/Al $_{0.35}$ Ga $_{0.65}$ As quantum well using two complementary experimental approaches: time-res…
