Dielectric properties of pure and lanthanum modified bismuth titanate thin films
(Elsevier B.V. Sa, 2008-04-24)
We investigated the dielectric properties of pure and lanthanum modified bismuth titanate thin films obtained by the polymeric precursor method. X-ray diffraction of the film annealed at 300 degrees C for 2h indicates a ...
Imprint behavior and polarization relaxation of PLZT thin films
(Taylor & Francis Ltd, 2018-01-01)
Thickness dependence of imprint and polarization dynamics of Pb1-xLax(Zr1-yTiy)(1-x/4)O-3 (PLZT) thin films is reported in this work. Asymmetries in the histograms of the local piezoresponse reveal an imprint effect in the ...
Durango apatite fission-track dating using length-based age corrections and neutron fluence measurements by natural thorium thin films and natural U-doped glasses calibrated through natural uranium thin films
(Elsevier B.V., 2002-08-01)
In this work, we present an approach for neutron fluence measurements based on natural thorium thin films and natural uranium-doped glasses calibrated through natural uranium thin films to be used for dating with the ...
Catalytic EC reaction at a thin film modified electrode
(Elsevier, 2013-01)
Numerical simulations of cyclic voltammograms corresponding to a catalytic EC reaction taking place at a thin film modified electrode are performed by way of finite difference method. Besides considering the chemical ...
One-dimensional analytical model for oxide thin film growth on Ti metal layers during laser heating in air
(2001-05-15)
This paper presents the theoretical and experimental results for oxide thin film growth on titanium films previously deposited over glass substrate. Ti films of thickness 0.1 μm were heated by Nd:YAG laser pulses in air. ...
The influence of crystallization route on the properties of lanthanum-doped Bi4Ti3O12 thin films prepared from polymeric precursors
(Elsevier B.V., 2004-11-15)
Pure and lanthanum-doped Bi4Ti3O12 thin films were deposited on Pt/Ti/SiO2/Si substrate using a polymeric precursor solution. The spin-coated films were specular and crack-free and crystalline after annealing at 700 degreesC ...
Size effects of polycrystalline lanthanum modified Bi4Ti3O12 thin films
(Pergamon-Elsevier B.V. Ltd, 2008-01-08)
The film thickness dependence on the ferroelectric properties of lanthanum modified bismuth titanate Bi3.25La0.75Ti3O12 was investigated. Films with thicknesses ranging from 230 to 404 nut were grown on platinum-coated ...
Polymeric precursor method to the synthesis of XWO(4) (X = Ca and Sr) thin films-Structural, microstructural and spectroscopic investigations
(Elsevier B.V. Sa, 2009-05-27)
Stoichiometric XWO(4) (X = Ca, and Sr) thin films were synthesized using the polymeric precursor method. In this soft chemical method, soluble precursors such as strontium carbonate, calcium carbonate and tungstic acid, ...
Photoluminescence in amorphous (PbLa)TiO3 thin films deposited on different substrates
(Elsevier B.V., 2002-09-01)
Pb1-XLaXTiO3 thin films, (X = 0.0; 13 and 0.27 mol%) were prepared by the polymeric precursor method. Thin films were deposited on Pt/Ti/SiO2/Si (1 1 1), Si (1 0 0) and glass substrates by spin coating, and annealed in the ...
Enhanced electrical property of nanostructured Sb-doped SnO2 thin film processed by soft chemical method
(Elsevier B.V., 2004-02-02)
The effect of the Sb addition on the microstructural and electrical conductivity of the SnO2 thin film was studied in this work. Experimental results show that the Sb addition allowed to control the grain size and electrical ...
