Growth and Characterization of Lead Zirconate Titanate (PZT) Thin Films
This paper explores how to prepare the Pb(ZrxTi1-x)O3(PZT) thin films by using the sol-gel method on a silicon substrate
then it tests the film characteristics by different methods. The solution with different compositions and proportions is designed according to the molecular formulas
and then the solution is coated on Titanium (Ti) or Platinum/Titanium (Pt/Ti) substrates. The X-ray diffraction (XRD) analysis is used to characterize the orientation and crystalline quality of the PZT thin films
and the Atomic Force Microscopy(AFM) is used to study their morphologies. The influences of different heat treatment temperatures on the crystalline quality and surface morphology are analyzed. Based on this
a Micro-electro-mechanical System(MEMS) process is developed for the PZT thin film structure to measure their ferroelectric properties
and a sawyer tower circuit is used to measure the polarization electric hysteresis. The results show that PZT thin films prepared by the sol-gel method have good ferroelectric property and morphologies at heat treatment of 400 ℃ and annealing treatment of 650 ℃
and can be applied to the PZT-based MEMS and nano devices.
