Abstract: The lateral piezoelectric response and Kelvin mode of individual perovskite islands, distinguished by radial spherulitic microstructure, in lead zirconate titanate thin films were studied. It has been shown that spherulitic islands are radially polarized, which is associated with a change in phase density during crystallization of the perovskite phase from the low-temperature pyrochlore phase.

Keywords: lead zirconate titanate thin films, radially radiant spherulitic structure, piezoforce microscopy.
