The research conducted by Prof. Hao Jianhua, Chair Professor of Materials Physics and Devices in the Department of Applied Physics, and Weng Fu Io, a research student from his group, was published in Nature Communications. The title of the research is "Direct Observation of Intrinsic Room-Temperature Ferroelectricity in 2D Layered CuCrP₂S₆". Their research studies the robust out-of-plane ferroelectricity in two-dimensional layered CuCrP₂S₆ at room temperature down to 2.6 nm, which is a potential candidate for realizing low-dimensional multiferroicity. Throughout this study, the origin of the robust ferroelectric behaviors at atomic perspective is revealed.
