AbstractThe multiple polarization states driven by polarization rotation could trigger giant piezoelectric responses in electromechanical sensors. Theoretically and experimentally, polarization rotation in ferroelectrics was contentiously reported in PbTiO3 thin films, which may result from low symmetric phases, flexoelectricity, or interfacial oxygen octahedral coupling. In this work, 5 nm PbTiO3 was grown on SrRuO3-buffered (001)- and (101)-oriented SrTiO3 substrates. By using piezoresponse force microscopy and (scanning) transmission electron microscopy, self-assembled PbTiO3 nanostructures with a triangular prism-shaped morphology (average width about 30 nm) were observed on the (100-oriented SrTiO3 substrate. Particularly, continuous polarization rotation state was confirmed in each PbTiO3 nanostructure, where the rotation angle is up to 90 approximately from the left side to the right side. In collaboration with phase-field simulations, it is proposed that the surface positive charge accumulation facilitates the formation of continuous polarization rotation. Piezoresponse force microscopy measurements indicate that these [101]PbTiO3 nanostructures with polarization rotation display a superior piezoelectric response compared with the [001]PbTiO3 thin film. These results not only shed light on understanding the polarization rotation mechanism in ferroelectrics but also are expected to provide useful information for developing the high performance of electromechanical devices.
