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.
