Interfacial ferroelectricity in marginally twisted 2D semiconductors [PDF]
Nature Nanotechnology, 2021 Twisted heterostructures of two-dimensional crystals offer almost unlimited scope for the design of new metamaterials. Here we demonstrate a room temperature ferroelectric semiconductor that is assembled using mono- or few-layer MoS2. These van der Waals

Ferroelectricity in biological building blocks: Slipping on a banana peel?
Journal of Advanced Dielectrics, 2023 Ferroelectricity in biological system has been anticipated both theoretically and experimentally over the past few decades. Claims of ferroelectricity in biological systems have given rise to confusion and methodological controversy.

Two-dimensional ferroelectricity in a single-element bismuth monolayer
Nature, 2023 A single-element ferroelectric state is observed in a black phosphorus-like bismuth layer, in which the ordered charge transfer and the regular atom distortion between sublattices happen simultaneously and ferroelectric switching is further visualized ...

Advanced Science, 2023 AbstractFreestanding slender fluid filaments of room‐temperature ferroelectric nematic liquid crystals are described. They are stabilized either by internal electric fields of bound charges formed due to polarization splay or by external voltage applied between suspending wires.
