Abstract:
We have used conventional and high-resolution transmission electron microscopy to investigate the microstruture of epitaxial, ferroelectric PbTiO 3 films grown by pulsed laser ablation on (001) MgO single crystals, and on MgO covered with epitaxial Pt or SrTiO 3 . Pronounced variations are found in the widths and lengths of a -axis-oriented domains in these films, although the volume fraction of a -axis-oriented material varies only weakly for the different types of samples. In addition, the films deposited onto Pt-coated MgO have a larger grain size than those deposited onto bare MgO or SrTiO 3 /MgO. Possible reasons for the variations in the distribution of a -axis-oriented material in these samples include differences in the elastic properties and electrical conductivities of the different substrate combinations.
