Abstract
We report charge retention in preferentially c-axis oriented ferroelectric Pb(Zr,Ti)O3 (PZT) thin films on LaNiO3 by electrostatic force microscopy. The surface charge density of the PZT films was observed as a function of time in a selected area where a region is single poled and another region is reverse poled. Retention behaviors of the regions are very different: the single-poled region shows a declined response and the reverse-poled region reveals a retained characteristic. Decay and retention mechanisms of the regions are explained by space-charge redistribution and trapping of defects in the films.
