Effect of the microwave oven on structural, morphological and electrical properties of SrBi4Ti4O15 thin films grown on Pt/Ti/SiO2/Si substrates by a soft chemical method
(Elsevier B.V., 2008-06-01)
Thin films of SrBi4Ti4O15 (SBTi), a prototype of the Bi-layered-ferroelectric oxide family, were obtained by a soft chemical method and crystallized in a domestic microwave oven. For comparison, films were also crystallized ...
Dielectric properties and microstructure of SrTiO3/BaTiO3 multilayer thin films prepared by a chemical route
(Elsevier B.V., 2001-04-02)
Multilayer thin films with perovskite structures were produced by the polymeric precursor method. SrTiO3/BaTiO3 (STO/BTO) multilayers were deposited on Pt(111)/Ti/SiO2/Si(100) substrates by the spin-coating technique and ...
Structural, ferroelectric, and optical properties of Pb0.60Ca0.20Sr0.20TiO3, Pb0.50Ca0.25Sr0.25TiO3 and Pb0.40Ca0.30Sr0.30TiO3 thin films prepared by the chemical solution deposition technique
(Elsevier B.V., 2014-09-01)
Perovskite ferroelectric Pb0.60Ca0.20Sr0.20TiO3, Pb0.50Ca0.25Sr0.25TiO3 and Pb0.40Ca0.30Sr0.30TiO3, thin films were deposited on Pt/Ti/SiO2/Si and (1 0 0) LaAlO3 substrates by a chemical solution deposition method. XRD ...
High dielectric constant of SrTiO3 thin films prepared by chemical process
(Kluwer Academic Publ, 2000-10-01)
SrTiO3 thin films were prepared by the polymeric precursor method and deposited by spin-coating onto Pt/Ti/SiO2/Si(100) substrates. The spin-coated films heat treated at 700 degrees C were crack-free, dense, and homogeneous. ...
Structural and electrical properties of SrBi2Nb2O9 thin films prepared by chemical aqueous solution at low temperature
(Elsevier B.V., 1999-07-01)
SrBi2Nb2O9 (SBN) thin films were prepared by the polymeric precursors method and deposited by dip coating onto Pt/Ti/SiO2/Si(100) substrates. The dip-coated films were specular and crack-free and crystallized during firing ...
Growth studies of thin films of BaTiO3 using flash evaporation
(Elsevier Ltd, 1998)
A flash evaporation technique was implemented to grow polycrystalline thin films of BaTiO3 onto Si(100) substrates, which were prepared with protective layers of SiO2 or Pt/TiW. X-ray diffraction and X-ray photoelectron ...
Ba1-xSrxTiO3 thin films by polymeric precursor method
(Elsevier B.V., 2000-05-01)
Stoichiometric Ba1-xSrxTiO3 (BST; x = 0.4) thin films were prepared by the polymeric precursor method. High quality polycrystalline films of BST with low roughness (approximate to 3 nm) were obtained from a Pt/Ti/SiO2/Si ...
Piezoelectric properties of Bi4Ti3O12 thin films annealed in different atmospheres
(Elsevier B.V., 2007-05-03)
Bismuth titanate (Bi4Ti3O12-BIT) films were evaluated for use as lead-free piezoelectric thin-films in micro-electromechanical systems. The films were grown by the polymeric precursor method on Pt/Ti/SiO2/Si (1 0 0) (Pt) ...
