Title: Piezoelectric and dielectric properties of Pb ( Zr , Ti ) O 3 ferroelectric bilayers

Abstract

The dielectric and piezoelectric properties of an epitaxial PbZr0.8Ti0.2O3/PbZr0.6Ti0.4O3 ferroelectric bilayer film were studied. Time-resolved synchrotron x-ray microdiffraction provided access to layer-specific structural information during electric-field-induced changes. The observed dielectric and electromechanical responses are consistent with a weak electrostatic polarization coupling and can be described using a thermodynamic model of epitaxial ferroelectric bilayers. The weak electrostatic coupling between ferroelectric layers can enable unusual tail-to-tail and head-to-head polarization configurations. X-ray measurements of the piezoelectric response of the ferroelectric bilayer at a microsecond time scale confirmed a possible tail-to-tail polarization domain configuration.
