Electrical de-poling and re-poling of relaxor-PbTiO3 piezoelectric single crystals without heat treatment [PDF]
Nature CommunicationsRe-poling of unexpected partially depoled piezoelectric materials conventionally needs to be first fully depoled through annealing above their Curie temperature to revive piezoelectric performances. Here, we investigated de-poling and re-poling of Pb(In1/

PEROVSKITES AND OTHER FRAMEWORK STRUCTURE CRYSTALLINE MATERIALS (BOOK' FIRST PAGES AND PREFACE)
Materials and Devices, 2021 Perovskites are among the most famous materials due to their exceptional properties: they present nearly all existing types of interesting properties, in particular as ferroics or multiferroics, they may be insulators, (super)conductors, or ...

Piezoelectric response of nanoscale PbTiO3 in composite PbTiO3−CoFe2O4 epitaxial films [PDF]
Applied Physics Letters, 2008 Piezoelectric properties of PbTiO3 in 1/3PbTiO3−2/3CoFe2O4 transverse epitaxial nanostructures on differently oriented SrTiO3 were analyzed using conventional and switching-spectroscopy piezoelectric force microscopy. The results confirmed that the individual PbTiO3 nanocolumns in the CoFe2O4 matrix exhibit a detectable piezoelectric response ...

Structural and dielectric study of the Na0.5Bi0.5TiO3–PbTiO3 and K0.5Bi0.5TiO3–PbTiO3 systems [PDF]
Journal of Materials Chemistry, 1997 A study of the Na 0.5 Bi 0.5 TiO 3 –PbTiO 3 and K 0.5 Bi 0.5 TiO 3 -PbTiO 3 systems has been carried out using X-ray diffraction, differential scanning calorimetry and dielectric measurements. The limits of the rhombohedral (Na 0.5 Bi 0.5 TiO 3 -rich side) and tetragonal (PbTiO 3 -rich side ...

Creating polar antivortex in PbTiO3/SrTiO3 superlattice
Nature Communications, 2021 While the role of PbTiO3 in PbTiO3/SrTiO3 superlattices has been widely studied, little attention is paid to possible polar topologies in SrTiO3.

Theory of PbTiO3, BaTiO3, and SrTiO3 surfaces [PDF]
Faraday Discussions, 1999 First-principles total-energy calculations are carried out for (001) surfaces of the cubic perovskite ATiO3 compounds PbTiO3, BaTiO3, and SrTiO3. Both AO-terminated and TiO2-terminated surfaces are considered, and fully-relaxed atomic configurations are determined.
