title: Properties of epitaxial, (001)- and (110)-oriented (PbMg1/3Nb2/3O3)2/3-(PbTiO3)1/3films on silicon described by polarization rotation.
abstract: Epitaxial (PbMg1/3Nb2/3O3)2/3-(PbTiO3)1/3(PMN-PT) films with different out-of-plane orientations were prepared using a CeO2/yttria stabilized ZrO2bilayer buffer and symmetric SrRuO3electrodes on silicon substrates by pulsed laser deposition. The orientation of the SrRuO3bottom electrode, either (110) or (001), was controlled by the deposition conditions and the subsequent PMN-PT layer followed the orientation of the bottom electrode. The ferroelectric, dielectric and piezoelectric properties of the (SrRuO3/PMN-PT/SrRuO3) ferroelectric capacitors exhibit orientation dependence. The properties of the films are explained in terms of a model based on polarization rotation. At low applied fields domain switching dominates the polarization change. The model indicates that polarization rotation is easier in the (110) film, which is ascribed to a smaller effect of the clamping on the shearing of the pseudo-cubic unit cell compared to the (001) case.
