Local piezoresponse and ferroelectric domain of sol-gel Pb(Zrx,Ti1-x)O3 film

Abstract

In this work Pb(ZrxTi1-x)O3 (PZT) films with different thicknesses and compositions were prepared by a sol-gel method. Surface morphology and nanoscale behavior of single domain were mainly investigated by the piezoresponse force microscopy. Island-like and sun-rays types of grain and ferroelectric domain structures were observed. Changes of local hysteresis loops and magnitudes of the piezoresponses of the PZT films with different thicknesses and at different domains were systematically investigated.
