Temperature dependence of dielectric properties for Ba(Zr0.25Ti0.75)O-3 thin films obtained from the soft chemical method
(Elsevier B.V., 2007-10-15)
Ba(Zr0.25Ti0.75)O-3(BZT) thin films prepared by the polymeric precursor method (PPM) were annealed at 500, 600, and 700 degrees C for 4h. All films crystallized in the perovskite structure present a crack-free microstructure. ...
Structure and ferro/piezoelectric properties of SrBi(4)Ti(4)O(15) films deposited on TiO(2) buffer layer
(Elsevier B.V. Sa, 2009-05-27)
TiO(2) buffer layer was introduced between SrBi(4)Ti(4)O(15) (SBTi) thin films and Pt bottom electrodes through the soft chemical solution. The obtained films were characterized by X-ray diffraction, atomic force microscopy ...
