Chalcogenide perovskites have shown great potential for photovoltaic applications. Most researchers begun to pay close attention the crystal synthesis, phase stability, and optoelectronic properties of chalcogenide AMX3 (A = Ca, Sr, Ba; M Ti, Zr, Hf, Sn; X S, Se). At present, A-site metal cations are mainly limited alkaline earth in literature. The replacement by Yb2+ is proposed as an alternative perovskites. In this study, mechanical, electronic, optical, novel chalcogenides YbMX3 (M Hf;...
Films of the Tl-Ba-Ca-Cu-O high Tc superconductor can be prepared by either two organometallic chemical vapor deposition routes. Ba-Ca-Cu-O films are first on yttria-stabilized zirconia using volatile precursors Ba(heptafluorodimethyloctanedionate)2, Ca(dipivaloylmethanate)2, and Cu(acetylacetonate)2. Deposition is carried out at 5 Torr pressure with argon as carrier gas water reactant gas. Thallium next incorporated in these diffusion bulk source, or Tl(cyclopentadienide) source. The latter...
${\mathrm{La}}_{1\mathrm{\ensuremath{-}}\mathit{x}}$${\mathrm{Sr}}_{\mathit{x}}$${\mathrm{CoO}}_{3}$ (LSCO) has recently been found to exhibit large magnetoresistance (MR) effect. In this paper, microstructures of LSCO thin films, which may provide important clues for understanding the unusual MR characteristics in these intrinsic magnetic oxides, were determined by transmission electron microscopy. An ordered, anisotropic perovskite-type structure n-LSCO was observed and its atomic model...
High-quality YBa2Cu3O7−x films were grown in situ on LaAlO3 (100) by a novel single liquid source plasma-enhanced metalorganic chemical vapor deposition (CVD) process. The complexes M (thd)n, (thd=2,2,6,6-tetramethyl-3-5-heptanedionate; M=Y, Ba, Cu) dissolved an organic solution and injected into vaporizer immediately upstream of the reactor inlet. technique dramatically simplifies current CVD processing can significantly improve process reproducibility. X-ray diffraction measurements...
Films of the high Tc Bi-Sr-Ca-Cu-O superconductor have been prepared by organometallic chemical vapor deposition using volatile metalorganic precursors Cu(acetylacetonate)2 , Sr(dipivaloylmethanate)2 and Ca(dipivaloylmethanate)2, triphenylbismuth. Deposition is carried out at 2 Torr with argon as carrier gas oxygen water reactants. Film growth rates 2–3 μm/h are achieved. After annealing under oxygen, energy dispersive x-ray analysis diffraction data reveal that such films on [100]...
Using the white line intensities, electron energy-loss spectroscopy in a transmission microscope has been employed to characterize valence conversion and oxygen vacancies La1−xCaxMnO3−y. For nominal doping composition x=0.33, ratio of Mn4+ Mn3+ is determined be more than 0.25 but less 0.5, content vacancy y no 0.065 (equivalent 2.2 at. % content). At ymax=0.065, 60% residual charge introduced by Ca balanced Mn3+to 40% vacancy.
Interface microstructures of BaTiO3/LaAlO3 grown by metalorganic chemical vapor deposition (MOCVD) are studied using high-resolution transmission electron microscopy (HRTEM). dislocations in have been shown to be directly linked up with the 90° domain boundaries BaTiO3. This association is a result strain relief due phase transformation when cooled down from growth temperature. The Burgers vector interface 〈010〉.
