Fig. 2 — a, b Circularly polarized PL spectra of PbI₂ and WS₂ in PbI₂/WS₂ heterostructures with different thicknesses. c Degree of polarization ρ of PbI₂ as a function of thickness of the heterostructures. The solid line represents the numerical simulation result. d, e Schematic illustrations of the resulting spin polarization in the thin and thick PbI₂/WS₂ heterostructures. The curled curves represent the incident light and the PL emissions. The red balls represent spin-down electrons, and the blue balls represent spin-up electrons.
