Structural, dielectric and ferroelectric properties of Nb-doped PZT thin films produced by oxide precursor method
(2002-01-01)
Recently, was proposed a chemical method for preparation of ferroelectric thin films based on oxide precursors. In this work, PZT thin films were prepared to attest the viability of this method for cation-substitution. In ...
Thickness dependence of structure and piezoelectric properties at nanoscale of polycrystalline PZT thin films
(2012-10-31)
Lead zirconate titanate Pb(Zr 0.50Ti 0.50)O 3 (PZT) thin films were deposited by a polymeric chemical method on Pt(111)/Ti/SiO2/Si substrates to understand the mechanisms of phase transformations and the effect of film ...

On the influence of pyrochlore phase on ferroelectric and dielectric properties of PZT thin films
(2020-02-17)
The intrinsic contribution of dielectric permittivity was obtained in thin films of PZT pyrolyzed at different temperatures. Pyrochlore phases were observed in films pyrolyzed at temperatures above 350 °C, while only the ...
Imprint effect in PZT thin films at compositions around the morphotropic phase boundary
(2016-08-31)
Piezoeresponse force microscopy (PFM) and local piezoresponse hysteresis loops were used to study the imprint effect in PbZr1-xTixO3 thin films at compositions around the morphotropic phase boundary (MPB). Schottky barriers ...
Role of residual stress on phase transformations of Pb(Zr0.50Ti0.50)O3 thin films obtained from chemical route
(2016-07-14)
abstract: The effects of heat treatment on the phase transformations of lead zirconate titanate Pb(Zr0.50Ti0.50)O3 (PZT) thin films were studied. The pyrolysis temperature directly affected the densification, residual ...
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 ...
Filmes finos de LaNiO3 e PZT preparados pelo métodos das soluções precursoras poliméricas e depositados em substratos de silício
(Universidade Estadual Paulista (Unesp), 2006-04-24)
Nesta tese estudou-se a preparação de filmes finos de PZT não dopados e dopados com Nióbio, depositados sobre substratos de Pt/Ti/SiO2/Si para aplicações em memórias não voláteis de acesso randômico (NVRAM) e memórias ...
