Intrinsic and Extrinsic Size Effects in Fine-Grained Morphotropic-Phase-Boundary Lead Zirconate Titanate Ceramics
TLDR
In this paper, the authors investigated the properties of lead zirconate titanate (PZT) ceramics over the grain-size range of 0.1-10 μm.Abstract:
The processing, electromechanical properties, and microstructure of lead zirconate titanate (PZT) ceramics over the grain-size range of 0.1-10 μm were studied. Using measurements over a large temperature range (15-600 K), the relative role of extrinsic contribution (i.e., domain-wall motion) was deduced to be influenced strongly by the grain size, particularly for donor-doped PZT. Analytical transmission electron microscopy studies were conducted to investigate the trend in domain configurations with the reduction of grain size. The correlations between domain density, domain variants, domain configurations (before and after poling), spontaneous deformation, and the elastodielectric properties were qualitatively discussed, leading to new insights into the intrinsic and extrinsic effects and relevant size effects in ferroelectric polycrystalline materials.read more

TL;DR: In this paper, a model is developed which proposes that each grain has a different transition temperature Tc. The Tc values are taken as following a Gaussian distribution and the behaviour of the dielectric constant against temperature is computed and checked with experimental results.

Electronic domain pinning in Pb(Zr,Ti)O3 thin films and its role in fatigue
TL;DR: In this article, it was shown that the suppressed polarization can be restored to essentially its initial polarization value by injecting electronic charge carriers into the ferroelectric, which strongly suggests that all three forms of degradation involve locking domains by electronic charge trapping centers.
