Abstract

A mechanism for the switching behaviors of ferroelectric thin films has been investigated using piezoresponse force microscopy (PFM), and PFM successfully visualized the magnitude and the phase of the domain. PbZr 1-xTixO3(PZT) thin films with a (111) texture were deposited onto commercial Pt/Ti/SiO2/Si substrates via the sol-gel technique. A combination of in-plane and outof-plane modes for PFM were used to reconstruct the three-dimensional polarization distribution, and the allowed domain configurations for the PZT films for different symmetries and different textures are illustrated schematically. Also, the domain and the domain switching properties were studied for PZT films with different compositions by applying a DC bias voltage to a localized area.
