The Rise of Ferroelectricity at Nanoscale: Nanoelectronics is rediscovering the ferroelectricity

open access: yesIEEE Nanotechnology Magazine, 2021
We present a comprehensive review of the emerging nanoscale ferroelectric materials used in novel nanoelectronics devices. First, we outline specific physical and electronic properties of ferroelectric materials, then we focus on two main classes of ferroelectrics based on hafnium oxide (HfO2) and 2D materials.

Ferroelectricity enhancement in ferroelectric nanotubes [PDF]

open access: yesPhase 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 ...

Fractional Quantum Ferroelectricity

open access: yesNature Communications, 2023
Abstract 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 polarization is determined by the point group of the ferroelectric.
