Electroresistance and electro-optic effects in molecular ferroelectrics

APL Materials, 2020
Molecular ferroelectrics are often considered as an alternative to inorganic ferroelectrics due to their structural diversity, optical transparency, and low-temperature solution processing.

Study of Constitutive Behavior of Ferroelectrics via Self-Consistent Modeling and Neutron Diffraction [PDF]

, 2007
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

Deciphering the atomic-scale structural origin for large dynamic electromechanical response in lead-free Bi0.5Na0.5TiO3-based relaxor ferroelectrics

Nature Communications, 2022
For relaxor ferroelectrics, correlating their properties and local structures is challenging. Here, the authors correlate the atomic-scale structure and the large dynamic electromechanical property in Bi0.5Na0.5TiO3-based relaxor ferroelectrics.

Wake-Up and Fatigue under Electrical Cycling in HfO₂-Based Ferroelectrics: Mechanisms and Strategies toward Reliable Devices. [PDF]

Adv Sci (Weinh)
HfO2‐based ferroelectrics exhibit wake‐up and fatigue behaviors during electrical cycling, significantly affecting device endurance and reliability. These phenomena are governed by defect dynamics, including oxygen vacancy redistribution and charge trapping.

Effectively control negative thermal expansion of single-phase ferroelectrics of PbTiO3-(Bi,La)FeO3 over a giant range [PDF]

, 2013
Control of negative thermal expansion is a fundamentally interesting topic in the negative thermal expansion materials in order for the future applications. However, it is a challenge to control the negative thermal expansion in individual pure materials
