High tunability in compositionally graded epitaxial barium strontium titanate thin films by pulsed-laser deposition
Compositionally graded barium strontium titanate @(BaxSr12x)TiO3—BST, x50.75, 0.8, 0.9, and 1.0# thin films are fabricated by pulsed-laser deposition on a LaAlO3 substrate with (La0.7Sr0.3)MnO3 as the bottom electrode. A high dielectric permittivity and temperature characteristic without Curie–Weiss law are obtained. A tunability of over 70% is obtained at frequency of 1 MHz, which is higher th...
متن کاملPhotoluminescence of barium titanate and barium zirconate in multilayer disordered thin films at room temperature.
The emission of wide band photoluminescence showed a synergic effect on barium zirconate and barium titanate thin films in alternate multilayer system at room temperature by 488 nm exiting wavelength. The thin films obtained by spin-coating were annealed at 350, 450, and 550 degrees C for 2 h. The X-ray patterns revealed the complete separation among the BaTiO3 and BaZrO3 phases in the adjacent...
متن کاملLow-Temperature Monoclinic Phase in Epitaxial (001) Barium Titanate on (001) Cubic Substrates
The possibility of the existence of a low temperature monoclinic phase in epitaxial (001) BaTiO3 films on a (001) compressive substrate is analyzed theoretically and compared to recent experimental data from literature. There is good agreement between the theoretical findings and the experimentally observed behavior. The formation of the monoclinic phase arises from the point group reduction du...
متن کاملTransport Properties of Epitaxial Lift Off Films
Transport properties of epitaxially lifted-off (ELO) films were characterized using conductivity, Hall and Shubnikov-de Haas measurements. A 10-15% increase in the 2D electron gas concentration was observed in these films as compared with adjacent conventional samples. We believe this result to be caused by a backgating effect produced by a charge build up at the interface of the ELO film and t...
متن کاملBarium Titanate Nanoparticles in Block Copolymer
Cubic BaTiO3 particles of∼10 nm were crystallized predominantly within the hydroxylated polybutadiene matrix of a phase separated triblock copolymeric thin film of polystyrene-polybutadiene-polystyrene (Kraton D1102). The barium titanated Kraton thin film had remnants of the cylindrical morphology of a plain Kraton thin film with an interdomain spacing of ∼23 nm. The procedure of barium titanat...
