Thermal stability studies of alternating current poled Pb(Mg1/3Nb2/3)O3-PbTiO3 single crystals grown by solid-state crystal growth

open access: yesMaterials Research Letters, 2023
Thermal stabilities of relaxor-PbTiO3 single crystals are of great importance due to their limited operational temperatures in devices. Herein, to elucidate how poling conditions influence thermal stabilities, we investigated direct current (DC) and ...

Enhancing polarization by electrode-controlled strain relaxation in PbTiO3 heterostructures

open access: yesAPL Materials, 2016
A large remanent polarization close to theoretical value 80 μC/cm2 of bulk PbTiO3 is achieved in epitaxial heterostructures of (120–600)-nm-thick PbTiO3 films grown by pulsed laser deposition on (001) SrTiO3 substrate using a 100-nm-thick SrRuO3 bottom ...

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

open access: yesActa 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.

Field‐Programmed Anisotropy in Magneto‐Piezoelectric Composites for Material‐Encoded Mechanoperception

open access: yesAdvanced Materials, EarlyView.
Field‐programmed anisotropy imparts material‐level intelligence to soft composites. Magnetic torque dynamics drive magneto‐piezoelectric nanowires from random dispersion into deterministic axial alignment. The resulting hierarchical percolation networks confine electromechanical coupling to specific axes and intrinsically decouple superposed force ...

Theoretical investigations of the bulk modulus in the tetra-cubic transition of PbTiO3 material

open access: yesQuímica Nova, 2014
Resulting from ion displacement in a solid under pressure, piezoelectricity is an electrical polarization that can be observed in perovskite-type electronic ceramics, such as PbTiO3, which present cubic and tetragonal symmetries at different pressures ...
