ABSTRACT
Many ways can be used to tune in-plane strains and thus to tailor the physical properties of ferroelectric films. Impact of effective shear strain on the equilibrium phases and polarization states of single-domain PbTiO3 thin film is investigated by a thermodynamic theory. The modeling results indicate that not only shear strain but also the orientations of polarization components produce profound impacts on the equilibrium phases of thin film, which is essentially different from the cases of S6=0. Different components of polarization can be controlled by temperature, in-plane strains, and especially shear strain.
