Structural and electromechanical study of Bi0.5Na0.5TiO3-BaTiO3 solid-solutions [PDF]

Processing and Application of Ceramics, 2013
Solid solution of (1-x)Bi0.5Na0.5TiO3–xBaTiO3 have been synthesized via conventional solid-state reaction route. Structural changes of the solid-solutions were investigated by using X-ray diffraction, Rietveld refinement Raman spectroscopy and ...

Unraveling the Effects of Depolarization in Ultrathin Barium Titanate. [PDF]

Adv Sci (Weinh)
This article employs synchrotron‐based spectroscopy, time‐resolved electrical measurements, and phase‐field simulations to establish reverse‐domain formation as the mechanism of polarization loss in ultrathin BaTiO3${\rm BaTiO}_3$ films as a critical obstacle to low‐voltage ferroelectric devices.

Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks. [PDF]

Adv Sci (Weinh)
Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,

Structural Origin of Morphotropic Phase Boundary in Advanced Perovskite Ferroelectric Oxides. [PDF]

J Am Chem Soc
Ferroelectric oxides PbZr1-xTixO3 (PZT) with the ABO3 perovskite structure exhibit exceptional polarization responses near their morphotropic phase boundary (MPB), yet the chemical origin of this behavior remains unclear. Here, we show that, in a prototypical composition, 0.05Pb(Mn1/3Sb2/3)O3-0.95PbZr0.52Ti0.48O3, this origin arises from coupled ...
