Optimization of seed layer of PbTiO3/PbZr0.3Ti0.7O3/PbTiO3 sandwich structure ferroelectric thin film

Acta Physica Sinica, 2008
The PT/PZT/PT and PZT thin films were prepared by sol-gel method. Different Pb content (x) (x=0, 005, 010, 015, 020) were added in excess to the PT precursor to optimize PT seed layer. The XRD and AFM results show that the crystalline phase and microstructure of the films were greatly affected by the excess Pb content (x) in PT layers.

Synergistically boosting charge separation and surface activity for efficient solar-powered cathodic metal protection

Carbon Neutrality
The escalating global energy demand has spurred the emergence of diverse solar-powered systems. As a typical example, photocathodic protection (PCP) is a promising technology to prevent metal corrosion via a “solar-electric-chemical” energy conversion ...

Manipulating topological transformations of polar structures through real-time observation of the dynamic polarization evolution

Nature Communications, 2019
Direct observation of the dynamic evolution of polar domain structures at atomic level remains challenging. Here, the authors report the observation of real-time topological transformations of polar structures in PbTiO3/SrTiO3 multilayers.

Domain Wall Orientations in Ferroelectric Superlattices Probed with Synchrotron X-Ray Diffraction

, 2018
Ferroelectric domains in PbTiO$_3$/SrTiO$_3$ superlattices were studied using synchrotron X-ray diffraction. Macroscopic measurements revealed a change in the domain wall orientation from $\left\lbrace 100 \right\rbrace $ to $\left\lbrace 110 \right ...

First Principles Theories of Piezoelectric Materials

, 2007
Piezoelectrics have long been studied using parameterized models fit to experimental data, starting with the work of Devonshire in 1954. Much has been learned using such approaches, but they can also miss major phenomena if the materials properties are ...
