BaTiO₃ as a Biased Paraelectric

Japanese Journal of Applied Physics, 1985
With the assumption that the ferroelectric tetragonal phase of BaTiO3 can be treated as a biased cubic phase, we have found the temperature dependence of the electrooptic coefficient and the electrostrictive coefficient.

Interface control in BaTiO 3 based supercapacitors

SPIE Proceedings, 2010
Core shell BaTiO 3 based particles sintered using advanced processes provide a high control of grain boundaries in bulk composites. As a result, supercapacitor behavior was evidenced which came from the balance between inner grain conductivity and grain boundary dielectric barrier.

Solubility of BaO in BaTiO ₃

Journal of the American Ceramic Society, 1985
The solubility and mode of incorporation for BaO in BaTiO 3 were studied by X‐ray powder diffraction, scanning and transmission electron microscopy, electron probe microanalysis, and equilibrium electrical conductivity measurements. The presence of barium orthotitanate, Ba

Nanotwins in BaTiO₃nanocrystals

Philosophical Magazine A, 1998
Abstract BaTiO3 nanocrystals, in which the coexistence of the high-temperature hexagonal phase with the cubic—tetragonal phase at room temperature was suggested in a previous study, have been investigated using high-resolution transmission electron microscopy.

Beam modulated fanning in a crystal BaTiO 3

SPIE Proceedings, 2011
Communication systems require devices that allow rapid distribution of signals to multiple users. We presented a proposal for a demultiplexer based on the fanning effect. Beam fanning is a process similar to two-beam coupling, except in this case, in where only one beam is incident on the material and its energy is transferred into scattered light ...

Nonstoichiometry in Undoped BaTiO ₃

Journal of the American Ceramic Society, 1981
Equilibrium electrical conductivity data for large‐grained, poly crystalline, undoped BaTiO 3 , as a function of temperature, 750° to 1000°C, and oxygen partial pressure, 10 −20 < P O2 < ...

The role of epoxy matrix occlusions within BaTiO 3 nanoparticles on the dielectric properties of functionalized BaTiO 3 /epoxy nanocomposites

Composites Part A: Applied Science and Manufacturing, 2016
Abstract In this work, the effects of controlled nanoparticles aggregations of barium titanate (BaTiO 3 ) on the dielectric properties of epoxy nanocomposites are investigated in detail with respect to different experimental parameters like frequency, ceramic content and temperature. Dispersing silanized BaTiO 3 nanopowder under ultrasonic and stir,

Epitaxial BaTiO₃crystals

Ferroelectrics, 1994
Abstract Epitaxial crystals of BaTiO3 have been grown by activated reactive evaporation. The ultra-thin crystal less than 100A thickness shows an elongation along the c-direction. The ferroelectric phase transition of the thin films is discussed in terms of the epitaxial effect and the surface layer.

Phase Conjugation In BaTiO 3 At 830 Nanometers

SPIE Proceedings, 1990
We have demonstrated self-pumped phase conjugation of semiconductor lasers at 830 nanometers in barium titanate using a self-contained geometry. The reflectivities and response times of this geometry are compared to those reported for self-pumped ring passive phase conjugate mirrors.

Optimal BaTiO₃ BaTiO₃ Cluster Formation for High Performance Piezoelectric Nanogenerators

ECS Meeting Abstracts, 2014
Several piezoelectric materials, including ZnO, BaTiO3, and PZT, have been widely investigated to develop high performance piezoelectric nanogenerators (NGs).1-3 In particular, the NGs based on BaTiO3 (BTO) nanoparticles (NPs) are of interest due to their excelling piezoelectric properties and environmentally safe nature.
