摘要：

We report on the structural, ferroelectric and optical properties of lead zirconate titanate (PZT) thin films (with a molar ratio of Zr:Ti::65:35) deposited by sol-gel technique on ITO-coated corning 7059 glass substrates. A seed layer of PbTiO3 (0.1 mu m) was coated by sol-gel on the substrates before depositing PZT. A metal/ferroelectric/metal (MFM) structure was used for electrical property measurements, formed by depositing gold electrodes on top of the film. The films were characterized for C-V, I-V, P-E and optical transmission. Relatively low remnant polarization (P-r = 3.6 mu C/cm(2)) was observed for the films. Value of optical band gap was found to be 3.4eV. The results are discussed. (c) 2005 Elsevier B.V. All rights reserved.
