Sputtered lead scandium tantalate thin films: Pb4+ in B sites in the perovskite structure

Ce doped BiFeO3thin films with a perovskite structure were prepared using solution-gelation method. It shows that the ferroelectric properties have been enhanced after doping Ce. The enhanced ferroelectric properties are attributed to the structural transformation and the reduced leakage current after doping rare metal of Ce. It has been found that the phase structures of the films transfer from rhombohedral symmetry structure to the coexistence of the tetragonal and orthorhombic symmetry structure. And Fe2+ions have been reduced, which leads to the decreased leakage for Ce doped BiFeO3thin films. The present work can provide an available way to improve the ferroelectric and leakage properties for multiferroic BiFeO3based thin films.

"Barium strontium Titanate (BST) is a solid solution consist of BaTiO3 and SrTiO3 that mixed with suitable ratio. Barium strontium Titanate oxide (Ba0.8Sr0.2TiO3) thin films prepared by sol gel technique. Barium strontium Titanate thin films deposited on Si substrate and annealed at [400,500, 600 and 700] ºC. The characterization of BST films investigated by a different technique, the X-Ray Diffraction (XRD) and Scanning Electron Macroscopy (SEM) revealed the phases, crystal structure and surface topography of the films. XRD pattern shows tetragonal phase for Ba0.8Sr0.2TiO3 perovskite structure with many peaks for different plans. The films annealed at the different temperature that indicated intermediate phases on perovskite structure of Ba0.8Sr0.2TiO3.

Copper-tin-oxide thin films have been prepared on quartz substrates by the magnetron sputtering method. The structural,optical and electrical properties were investigated. The prepared samples were amorphous, CuSnO3 single crystalline grains with perovskite structure were observed after annealing temperature was above 530°C. The optical and electrical properties had great dependence with reactive gas pressure and annealing temperature. Thermal probe reveals p type conductivity of some samples.
