Amorphous BaTiO3 layers deposited on SrTiO3 (001) substrates at room temperature were subsequently crystallized using solid phase epitaxy (SPE). Heating an initially amorphous layer in air 650 °C for 3 h resulted crystallization with components two distinct crystallographic orientation relationships respect to the substrate. Part of volume a cube-on-cube relationship Other volumes four variants...

Above-bandgap femtosecond optical excitation of a ferroelectric/dielectric BaTiO3/CaTiO3 superlattice leads to structural responses that are consequence the screening strong electrostatic coupling between component layers. Time-resolved x-ray free-electron laser diffraction shows response includes net lattice expansion consistent with depolarization-field driven by photoexcited charge carriers....

BaTiO3 exhibits several functional properties, such as high dielectric constant, large Pockels coefficient, and strong ferroelectricity/piezoelectricity. These properties can be used for a variety of applications, ferroelectric tunnel junctions in non-volatile memory devices. To achieve large-scale integration BaTiO3, however, one requires the synthesis high-quality films at low temperatures or...

Solid-state reaction between BaTiO3 and Fe2O3 was used to produce a multiferroic heterostructure composite. Commercial Fe(NO3)3?9H2O were suspended in ethanol for 30 minutes an ultrasound bath. The prepared mixture thermally processed at 300?C 6 h. Sintering 1300?C 1 h resulted of different phases, BaTiO3, BaFe12O19 Ba12Ti28Fe15O84, which confirmed by x-ray powder diffraction. A dense microstru...

Ferroelectric properties of films can be tailored by strain engineering, but a wider space for property engineering opened including crystal anisotropy. Here, we demonstrate huge anisotropy in the dielectric and ferroelectric BaTiO3 films. Epitaxial deposited on (100), (110), (111) SrTiO3 substrates were fabricated chemical solution deposition. The tensile-strained due to thermal confirmed enha...

Nanocomposites containing components with semiconductor, ferroelectric, and ferromagnetic properties have attracted considerable attention of specialists due to the range possible applications, including catalysis electrocatalysis, electrode materials for solar fuel cells, capacitors, electrical biosensors, anti-corrosion coatings much more. In recent years, both fundamental applied interest in...

We examine the photo-assisted polarization loop in a BiFeO3 thin film under UV light illumination. BiFeO3 thin film prepared by pulsed laser deposition method onto the BaTiO3 thin film and the polarization behavior has been measured under poling voltage. Our results show the engineered polarization due to controllable schottky barrier under inverse poling voltage. This control on schottky barri...
