Investigation of defects dependence of local piezoelectric response on Fe, La-modified (Pb,Sr)TiO3 thin films: A piezoresponse force microscopy study
(Elsevier B.V., 2018-08-01)
In this study, undoped-(Pb,Sr)TiO3 and Fe3+, La3+ co-doped (Pb,Sr)TiO3 thin films were investigated at the nanoscale level by piezoresponse force microscopy (PFM), in order to evaluate the impact of doping induced damages ...
BiVO4 thin film preparation by metalorganic decomposition

Gas sensing and conductivity relationship on nanoporous thin films: A CaCu3Ti4O12 case study
(2016-04-01)
In this work, CaCu3Ti4O12 (CCTO) thin films were synthesized with the polymeric precursor method and characterized by structural (X-ray diffraction) and morphological (scanning electron microscopy) techniques. These films ...
Structural study of thin films prepared from tungstate glass matrix by Raman and X-ray absorption spectroscopy
(Elsevier B.V., 2008-06-30)
Thin films were prepared using glass precursors obtained in the ternary system NaPO(3)-BaF(2)-WO(3) and the binary system NaPO(3)-WO(3) with high concentrations of WO(3) (above 40% molar). Vitreous samples have been used ...
Effect of thermal treatment temperature on the crystallinity and morphology of LiTaO3 thin films prepared from polymeric precursor method
(Kluwer Academic Publ, 2004-07-01)
Lithium tantalate thin films (LiTaO3) with (50:50) stoichiometry were prepared by spin coating method using a polymeric organic solution. The films were deposited on silicon (100) substrates with 4 layers. The substrates ...
Retention characteristics of lanthanum-doped bismuth titanate films annealed at different furnaces
(Elsevier B.V. Sa, 2009-05-15)
Lanthanum-doped bismuth titanate thin films (Bi(3.25)La(0.75)Ti(3)O(12) - BLT) were prepared by the polymeric precursor method and crystallized in the microwave and conventional furnaces. The obtained films are polycrystalline ...
Preparation of Pb(Zr,Ti)O-3 thin films by soft chemical route
(Elsevier B.V., 2004-09-01)
Lead zirconate titanate, Pb(Zr0.3Ti0.7)O-3 (PZT) thin films were prepared with success by the polymeric precursor method. Differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Fourier-transform infrared ...
Grazing incidence X-ray diffraction and atomic force microscopy analysis of BaBi2Ta2O9 thin films
(Elsevier B.V., 2002-08-01)
Thin films of BaBi2Ta2O9 (BBT) composition were prepared through the metal organic decomposition method. The crystallinity, phase formation, crystallite size and morphology of the thin films were measured as a function of ...
Ferroelectric and structural instability of (Pb,Ca)TiO3 thin films prepared in an oxygen atmosphere and deposited on LSCO thin films which act as a buffer layer
(ElsevierAmsterdam, 2014-04)
Structural, microstructural and ferroelectric properties of Pb0.90Ca0.10TiO3 (PCT10) thin films deposited using La0.50Sr0.50CoO3 (LSCO) thin films which serve only as a buffer layer were compared with properties of the ...
