Now, a new study shows that ferroelectricity can be imparted on a non-ferroelectric material if its stacked together—a concept known as proximity ferroelectricity. This could help make data ...

"A large number of few-layer van der Waals materials, including boron nitride and transition metal dichalcogenides (TMDs), show the curious phenomenon of sliding ferroelectricity," Chaudhary and ...

A detailed ab initio model of ferroelectric ordering in thin films shows that phase transitions and ferroelectric bistability occur down to diameters of 3.2 nm in nanodisks and nanorods.

a, AFM image of 2D vermiculite. b, PFM amplitude map of 2D vermiculite. c, PFM phase map of 2D vermiculite. d. Comparison of electric field responsivity of 2D vermiculite LC and other media.

Ferroic orders include ferromagnetism (spontaneous magnetic ordering), ferroelectricity (spontaneous electric polarization), ferroelasticity (spontaneous strain), and ferrotoroidicity (spontaneous ...

“Bilayers of two-dimensional van der Waals materials that lack an inversion center can show a novel form of ferroelectricity, where certain stacking arrangements of the two layers lead to an ...
