Study of Constitutive Behavior of Ferroelectrics via Self-Consistent Modeling and Neutron Diffraction [PDF]
The central goal of this study is to develop a reliable self-consistent model to describe the constitutive behavior of polycrystalline ferroelectrics and to predict their lattice strain and texture evolution. Starting with the model developed by Huber et

Porous (Ba,Sr)TiO3 ceramics for tailoring dielectric and tunability properties: Modelling and experiment [PDF]
3D Finite Element Method simulations were employed in order to describe tunability properties in anisotropic porous paraelectric structures. The simulations predicted that properties of a ceramic can be tailored by using various levels of porosity ...

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