Precipitation Hardening in Ferroelectric Ceramics. [PDF]

Adv Mater, 2021
AbstractDomain wall motion in ferroics, similar to dislocation motion in metals, can be tuned by well‐concepted microstructural elements. In demanding high‐power applications of piezoelectric materials, the domain wall motion is considered as a lossy hysteretic mechanism that should be restricted.

Counterfeit band gaps caused by microstructural voids in photo-ferroelectric ceramics

Open Ceramics, 2021
In recent years, conventional wide band gap ferroelectric ceramics have been engineered by doping to obtain reduced band gaps. The band gaps in these engineered ceramics are usually determined according to the optical absorption measurement.

Modeling polarization switching response of ferroelectric ceramics based on multiple natural configuration theory

Applications in Engineering Science, 2023
Ferroelectric ceramics experience polarization switching, which is macroscopically shown by nonlinear hysteretic responses when subjected to high compressive stresses and/or high amplitude of the electric field. We model the nonlinear hysteretic response
