Ferroelectricity enhancement in ferroelectric nanotubes [PDF]
Phase Transitions, 2007 In this paper we study the size effects of the ferroelectric nanotube phase diagrams and polar properties allowing for effective surface tension and depolarization field influence. The approximate analytical expression for the paraelectric-ferroelectric transition temperature dependence on the radii of nanotube, polarization gradient coefficient ...

Across‐Layer Sliding Ferroelectricity in 2D Heterolayers [PDF]
Advanced Functional Materials, 2022 Although the monolayers of most 2D materials are non‐ferroelectric with highly symmetric lattices, symmetry breaking may take place in their bilayers upon some stacking configuration, giving rise to so‐called sliding ferroelectricity where the vertical ...

Scale-free ferroelectricity induced by flat phonon bands in HfO2
Science, 2020 The atomic-scale structure of hafnium oxide explains ferroelectric properties for very thin films. Switching to the atomic scale Ferroelectric materials are attractive because they provide a way to change electrical resistance by using an electric field.

Ab Initio Study of Ferroelectric Critical Size of SnTe Low-Dimensional Nanostructures
Nanomaterials, 2020 Beyond a ferroelectric critical thickness of several nanometers existed in conventional ferroelectric perovskite oxides, ferroelectricity in ultimately thin dimensions was recently discovered in SnTe monolayers.
