Strain-tunable antiferroelectricity in 2D CuCrP 2 S 6 for high-performance neuromorphic devices

-axis, forming stripe-like FE domains. Band structure analysis reveals significant anisotropy in the electronic properties of the AFE-I phase, while magnetic anisotropy is also present, albeit with a smaller magnitude. This anisotropy enables phase and FE domain pattern identification using electrical properties. Additionally, we demonstrate possible polarization switching pathways through different AFE states, outlining the broad landscape of available intermediate FE states and domain kinetics inherent to CCPS. These findings highlight the untapped potential of not only CCPS but also other AFE materials for application in next-generation neuromorphic and electronic systems, offering new avenues for device functionality and design.
