Optimization of electro-strain and ferroelectric properties of P(VDF-TrFE) films under the synergistic effect of PTO nanosheets and in-situ electrostatic field

Journal of Materiomics
Traditional ferroelectric materials, such as lead zirconate titanate (PZT) ceramics, exhibit positive strain when subjected to an electric field along the polarization direction.

Super-Lattice Structure and Phase Evolution of Pb(Lu0.5Nb0.5)O3-PbTiO3 Single Crystal with Low PbTiO3

Crystals, 2018
The phase diagram of the Pb(Lu0.5Nb0.5)O3-PbTiO3 (PLN-PT) binary system was previously reported based on XRD and dielectric measurements results. Unusually, the Curie temperature of PLN-PT with low PT obtained from the phase diagram is much lower than ...

Diffraction contrast analysis of 90° and 180° ferroelectric domain structures of PbTiO3 thin films

Science and Technology of Advanced Materials, 2011
The ferroelectric domain structure of a PbTiO3 thin film on (100) SrTiO3 has been investigated by transmission electron microscopy (TEM). Two types of a-domain were found: one extended through the film to the surface and another comprised small a-domains

Electrocaloric effects in ferroelectrics and multiferroics from first principles

Journal of Materiomics
The electrocaloric (EC) effect characterizes the change in temperature or entropy of a material under the application of an external electric field. Ferroelectric and multiferroic materials have attracted considerable interest due to their potential for ...

Configuration and local elastic interaction of ferroelectric domains and misfit dislocation in PbTiO3/SrTiO3 epitaxial thin films

Science and Technology of Advanced Materials, 2011
We have studied the strain field around the 90° domains and misfit dislocations in PbTiO3/SrTiO3 (001) epitaxial thin films, at the nanoscale, using the geometric phase analysis (GPA) combined with high-resolution transmission electron microscopy (HRTEM)
