Abstract

A combination of vertical and lateral PFM revealed the domain orientation of the underlying PZT thin film and allowed mapping of the three-dimensional polarization of (111)-oriented 1x1.5-μm2 PZT capacitors. It was found that the poled capacitors, which appear as uniformly polarized in VPFM, were in fact in a polydomain state as was detected by LPFM. Despite the polycrystallinity of the PZT layer, regions larger than the average PZT grain size were found to have the same polarization orientation.
