Abstract
As a type of promising hardware for next-generation artificial visual systems with extended perceptual and anti-interference capabilities, circular-polarization-resolved retinomorphic sensors are underexplored due to the lack of suitable chiral materials that enable highly dissymmetric circular-polarization responses and multiple biomimetic functions. Here, we demonstrate a self-assembly heterogeneous microstructure consisting of chiral-deficient grains and chiral-rich grain boundaries in chiral perovskites that simultaneously facilitate spin selectivity and optoelectronic properties for highly dissymmetric and multifunctional circular-polarization-resolved retinomorphic sensors. Our sensors not only exhibit a photocurrent dissymmetry factor as high as 1.98 and a panchromatic circular-polarization-resolved response, but also possess multiple biomimetic functions that simulate human retinas, including synaptic behaviors, light adaptation, and color recognition. As a proof-of-concept, we respectively demonstrate their applications using a sensor array that resolves a single circular-polarization handedness for information encryption, as well as binocular sensor arrays that resolve the opposite circular-polarization handedness for virtual stereoscopic reconstruction.
