Fractional quantum ferroelectricity

Nature Communications, 2023
For an ordinary ferroelectric, the magnitude of the spontaneous electric polarization is at least one order of magnitude smaller than that resulting from the ionic displacement of the lattice vectors, and the direction of the spontaneous electric ...

Enhanced superconductivity and coexisting ferroelectricity at oxide interfaces. [PDF]

Nat Commun
The coexistence of superconductivity and ferroelectricity is rare due to their conflicting requirements: superconductivity relies on free charge carriers, whereas ferroelectricity typically occurs in insulating systems.

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.

Biferroelectricity of a homochiral organic molecule in both solid crystal and liquid crystal phases

Nature Communications, 2022
Ferroelectricity normally exists in either solid crystals or liquid crystals. Here, the authors report a homochiral organic compound which shows ferroelectricity in both solid crystal and liquid crystal phases.

Pressure-induced ferroelectric-like transition creates a polar metal in defect antiperovskites Hg3Te2X2 (X = Cl, Br)

Nature Communications, 2021
Generally, ferroelectricity in ABO3 perovskites is suppressed by hydrostatic compression, but the evidence for pressure-induced ferroelectricity remains elusive. Here, the authors find a direct ferroelectric-like structural transition induced by pressure

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.

A ferroelectric memristor [PDF]

Nature Materials, 2012
Memristors are continuously tunable resistors that emulate synapses. Conceptualized in the 1970s, they traditionally operate by voltage-induced displacements of matter, but the mechanism remains controversial. Purely electronic memristors have recently emerged based on well-established physical phenomena with albeit modest resistance changes.
