| Abstract | PZT films with different microstructure and Zr:Ti ratios were fabricated on ITO/glass and platinized silicon wafer substrates by dip-coating. A dense film of 2% porosity and a porous film of 19% porosity were obtained by repetition of thin and thick coatings, respectively. Development of pores during heating the film was examined and heating process factors were investigated. In the film fabricated on ITO/glass substrates, an existence of non-perovskite and low permittivity layer was confirmed by measurement of film thickness dependence of the dielectric constant. Among the films studied, the film with molar composition of Ti:Zr = 5:5 exhibited the largest dielectric constant and apparent piezoelectric coefficient, d33, though the values were small. Apparent piezoelectric coefficients of d33 and g33 of the porous films were larger than those of the dense films. |
