Photoluminescence behavior in MgTiO3 powders with vacancy/distorted clusters and octahedral tilting
(Elsevier B.V. Sa, 2009-09-15)
MgTiO3 powders were prepared by the complex polymerization method and heat treated at different temperatures for 2 h. These powders were analyzed by X-ray diffraction (XRD), Rietveld refinements, micro-Raman (MR) spectroscopy, ...
Metal-insulator transition in Nd1-xEuxNiO 3 compounds
(2006)
Polycrystalline Nd1-xEuxNiO3 (0≤x≤0.5) compounds were synthesized in order to investigate the character of the metal-insulator (MI) phase transition in this series. Samples were prepared through the sol-gel route and ...
Improvement of the dielectric and ferroelectric properties in superlattice structure of Pb(Zr,Ti)O-3 thin films grown by a chemical solution route
(American Institute of Physics (AIP), 2004-06-28)
Making heterolayered perovskite materials constitutes an approach for the creation of better dielectric and ferroelectric properties. In the experiment reported here, heterolayered PZT40/PZT60 films were grown on Pt/Ti/SiO2/Si ...
Novel SrTi1-xFexO3 nanocubes synthesized by microwave-assisted hydrothermal method
(Royal Soc Chemistry, 2012-01-01)
We report herein for the first time a facile synthesis method to obtain SrTi1-xFexO3 nanocubes by means by a microwave-assisted hydrothermal (MAH) method at 140 degrees C. The effect of iron addition on the structural and ...
Study on the orientation degree of Pb1-xLaxTiO3 thin films by the rocking curve technique and its morphological aspects
(Elsevier B.V., 2007-04-02)
Thin films of perovskite-type materials such as PbTiO3, BaTiO3, (Pb,La)TiO3, (Pb, La)(ZrTi)O-3, KNbO3, and Pb(Mg,Nb)03 have been attracting great interest for applications like non-volatile memories, ultrasonic sensors and ...
Study of the dielectric and ferroelectric properties of chemically processed BaxSr1-xTiO3 thin films
(Elsevier B.V., 2001-05-01)
Polycrystalline BaxSr1-xTiO3 (x = 0.4 and 0.8) thin films with a perovskite structure were prepared by the polymeric precursor method on a platinum-coated silicon substrate. High-quality thin films with uniform composition ...
Effect of the heat flux direction on electrical properties of SrBi2Nb2O9 thin films crystallized using a microwave oven
(Elsevier B.V., 2004-03-30)
Ferroelectric SrBi2Nb2O9 (SBN) thin films were prepared by the polymeric precursors method and deposited by spin coating onto Pt/Ti/SiO2/Si substrate and crystallized using a domestic microwave oven. It was studied the ...
Microstructural, dielectric and ferroelectric properties of calcium-modified lead titanate thin films derived by chemical processes
(Elsevier B.V., 2001-08-01)
Ferroelectric Pb1-xCaxTiO3 (x = 0.24) thin films were formed on a Pt/Ti/SiO2/Si substrate by the polymeric precursor method using the dip-coating technique for their deposition. Characterization of the films bq X-ray ...
Syntheses of bismuth titanate templates obtained by the molten salt method
(2013-09-01)
Bismuth titanate templates (Bi4Ti3O12) were synthesized by the molten salt method in Na2SO4 and K2SO4 fluxes, using an amorphous Bi4Ti 3O12 precursor and a mechanically mixed Bi 2O3+TiO2 mixture as the starting materials. ...
