The effect of the movable electrode on a piezoelectric-induced (PEI) image was discussed. By applying dc voltage between the movable electrode and the Pt bottom electrode, local polarization was induced on a lead zirconate titanate (PZT) thin film using an atomic force spectroscopy. A PEI image was obtained in the second pass in piezo-response mode where sample surface was scanned by applying ac voltage between the AFM tip and Pt bottom electrode at the sample displacement. It was shown that PEI images of various sample displacement were obtained and analyzed using force-sample displacement curves.
