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.

Domain Engineering in Bulk Ferroelectric Ceramics via Mesoscopic Chemical Inhomogeneity. [PDF]
Adv Sci (Weinh), 2022 Domain engineering in ferroelectrics endows flexibility for different functional applications. Whereas the domain engineering strategy for single crystals and thin films is diverse, there is only a limited number of strategies for bulk ceramics.

Textured ferroelectric ceramics with high electromechanical coupling factors over a broad temperature range. [PDF]
Nat Commun, 2021 The figure-of-merits of ferroelectrics for transducer applications are their electromechanical coupling factor and the operable temperature range. Relaxor-PbTiO 3 ferroelectric crystals show a much improved electromechanical coupling factor k 33 (88~93%)

Absence of ferroelectricity in BiMnO3 ceramics [PDF]
Journal of Applied Physics, 2012 We performed factor-group analysis of all phonons in possible monoclinic C2/c and C2 structures of BiMnO3 and compared it with our experimental infrared and Raman spectra.

A Mesoscopic Electromechanical Theory of Ferroelectric Films and Ceramics [PDF]
, 2002 We present a multi-scale modelling framework to predict the effective electromechanical behavior of ferroelectric ceramics and thin films. This paper specifically focuses on the mesoscopic scale and models the effects of domains and domain switching ...

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.
