Direct observation of BaTiO3 microcrystallites in thin amorphous BaTiO3 films
Applied Physics Letters, 1991Well separated BaTiO3 microcrystallites were observed by transmission electron microscopy (TEM) in rapidly annealed, amorphous BaTiO3 thin films. The crystallization temperature for amorphous BaTiO3 is between 400 °C and 500 °C.

Influence of BaTiO3 on Magnetic and Transport Properties of La0.7Sr0.3MnO3-BaTiO3 Nanocomposite
Journal of Superconductivity and Novel Magnetism, 2018La0.7Sr0.3MnO3 (LSMO)-BaTiO3 (BTO) nanocomposites have been synthesized by adding different amounts of BTO using the sol-gel method. The structural analysis confirms that both phases coexist in the composite samples with the rhombohedral and tetragonal structure for LSMO and BTO, respectively.

Dielectric and optical properties of BaTiO3/SrTiO3 and BaTiO3/BaZrO3 superlattices
Journal of Applied Physics, 2002BaTiO 3 (BTO)/SrTiO3 (STO), and BaTiO3/BaZrO3 (BZO) artificial superlattices were fabricated by the molecular beam epitaxy process and their dielectric properties and refractive indices were measured. Superlattices formed on Nb-doped STO substrates showed large leakage currents in comparison with those on pure STO substrates.

Abstract Highly (110)-oriented trilayered BaTiO 3 (25 nm) /(Na 0.5 Bi 0.5 ) 0.94 Ba 0.06 TiO 3 (300 nm) / BaTiO 3 (25 nm) thin films were deposited on Pt/Ti/SiO 2 /Si substrates via chemical solution deposition. It was found that the inserted bottom BaTiO 3 layer between Pt and (Na 0.5 Bi 0.5 ) 0.94 Ba 0.06 TiO 3 is very effective for promoting ...

Structural studies of BaTiO3:Er3+ and BaTiO3:Yb3+ powders synthesized by hydrothermal method
Journal of Rare Earths, 2014Erbium and ytterbium doped barium titanate nanopowders were prepared using the hydrothermal method. A barium titanate structure doped with rare earth ions manifested new characteristics and improved the field of application of optical devices such as trichromatic tubes, LCD displays, lamps, and infrared lasers. In this work, BaTiO3:Er3+ and BaTiO3:Yb3+

Dispersion of BaTiO3 powders (part I)
Ceramics International, 1984Abstract The fundamental properties of BaTiO 3 dispersions in pure organic liquids and water were studied by sediment volume and contact angle measurements. The liquid groups included alcohols, aldehydes, acids, esters, ketones, ethers, hydrocarbons, and water.

Effects of BaTiO3 on dielectric behavior of BaTiO3–Ni–polymethyl methacrylate composites
Applied Physics Letters, 2006Effects of ferroelectric BaTiO3 particles were investigated on the dielectric behavior of BaTiO3–Ni–polymethyl methacrylate composites fabricated by a two-step mixing and hot-molding method. The percolation power law in the smearing region was employed to explain the experimental results. The composites exhibit the dependence of the dielectric constant,

Abstract We have investigated the effect of coupling agents with different organic moiety on the dielectric properties of polyimide/BaTiO 3 (70 nm) composite films. INAAT (isopropyl tris( N -amino-ethyl aminoethyl)titanate, KR 44) and APTS (3-amino-propyl-triethoxysilane) were used as coupling agents, respectively, for homogeneous dispersion of ...

An attempt was made to retard the dissolution of Ba ions from BaTiO3 by coating Y compounds on the BaTiO3 particle surface. A hysteresis in the electrokinetic behavior of as-received BaTiO3 occurred during sequential acid and base titrations, while there was no hysteresis in the Y-coated BaTiO3. In the bare BaTiO3, dissolved Ba ions are adsorbed and/or

Abstract The Raman spectrum of BaTiO3 is investigated in the tetragonal and the cubic phase, where it is found that two strong transitions are still present. The temperature dependence of the intensities for the lines perculiar to the tetragonal phase correlates well with the presence of a tetragonal distortion.
