Spin dynamics of electrons, holes, and excitons in lead-halide perovskite semiconductors
dominant spin relaxation mechanisms [2,3,4]. Exciton spin polarization at cryogenic temperatures in bulk perovskite crystals with near-cubic (FA₀.₉Cs₀.₁PbI₂.₈Br₀.₂, FAPbBr₃) and orthorhombic (MAPbI₃, CsPbBr₃) [...] indicating strong spin selectivity and efficient spin initialization under circularly polarized excitation [2,3,5]. Spatial confinement of excitons in CsPbI₃ nanocrystals leads to a regime in which spin properties [...] Physical Properties and Applications. (eds. Z. V. Vardeny and M. C. Beard) (World Scientific,2022). [2] N. E. Kopteva, et al., Highly-polarized emission provided by giant optical orientation of exciton spins …
