| Popis: | The orientation of polarization in ferroelectric thin films is important for applications of these materials in nonvolatile memory and field-effect transistors with ferroelectric gates, and in catalysis and photocatalysis. One means of control is to choose a well defined substrate, but the influence of a substrate's electronic properties on polarization orientation is not well understood. In this investigation of model systems, the experimental findings are integrated with electrostatic models to determine the magnitudes and orientations of the interfacial electric fields that are useful for setting the polarization of the thin ferroelectric epilayer. |
