ABSTRACT
A lead titanate epitaxial thin film was obtained on a strontium ruthenium oxide bottom electrode by the hydrothermal method. The reaction temperature was 150°C more than 400 degrees lower than that of the conventional deposition processes. X-ray diffraction measurements revealed a c-axis of orientation. The single-crystal-like DE hysteresis curve showed a remanent polarization of 96.5 μC/cm2. The domain direction was controlled by an applied electric field using a metal-coated atomic force microcopy cantilever probe and the domain pattern was observed by scanning nonlinear dielectric microscopy. This investigation verified that this film did not contain an a-domain. In addition, no defects such as domain or grain boundaries were observed, even on the nanoscale.
