Two-dimensional ferroelectric(2D-FE)materials that characterize the spontaneous ferroelectricity down to monolayer limit and rich ferroic properties arising from FE orderings,have been extensively explored as low-dimensional sensor,electric and memory *** current work,group-IV transition metal oxide dihalide MOX_(2)(M=Zr and Hf,X=Cl,Br and I)monolayers have been identified as a new group of 2D-FE *** the comprehensive first-principles calculations combined with finite temperature Monte Carlo(MC)and ab initio molecular dynamics(MD)simulations,we investigate the temperature stability of FE polarization and further uncover the unique properties associated with spontaneous ferroelectricity of MOX_(2) *** particular,ZrOI_(2) monolayer,a promising 2D-FE material with room temperature stable ferroelectricity,semiconducting electronic structure and optoelectronic response under visible light,offers an ideal material platform to investigate the coupling of intrinsic anisotropy,optical absorption selectivity and spin degree of freedom with 2D ***,significant optical absorption anisotropy and giant linear dichroism effect are predicted for a 2D optical polarizer device based on ZrOI_(2) monolayer,where the adsorption of incident monochromatic linearly polarized light(hv=3.23 eV)along two planar directions with a nearly 100%optical selectivity can be ***,the spin–orbit coupling(SOC)induced spin splitting of valence band edges and out-of-plane textured spin configuration occur in ZrOI_(2) *** the meanwhile,the unidirectional spin–orbit field protected by C2v wave-vector point group can further create the persistent spin helix(PSH)state,leading to the extraordinarily long spin carrier *** importantly,the nonvolatile control of PSH state via the electric field induced polarization reversal has also been demonstrated for FE-ZrOI_(2) monolayer,which manifests as a great advantage for applications of
