Polarization-locked chiral persistent spin textures in two-dimensional lead-halide perovskites

Palanichamy Gayathri, Biplab Sanyal, Jonas Fransson

Chiral spacer cations crystallize two-dimensional hybrid perovskites in the polar Sohncke group $P{2}_1$, which places the polar axis in the inorganic layer. We analyze the spin-orbi…
