General Theory for Bilayer Stacking Ferroelectricity. [PDF]
Physical Review Letters, 2022 Two-dimensional (2D) ferroelectrics, which are rare in nature, enable high-density nonvolatile memory with low energy consumption. Here, we propose a theory of bilayer stacking ferroelectricity (BSF), in which two stacked layers of the same 2D material ...

0D van der Waals interfacial ferroelectricity
Nature Communications, 2023 The dimensional limit of ferroelectricity has been long explored. The critical contravention is that the downscaling of ferroelectricity leads to a loss of polarization.
