In this article, we reported a solution epitaxy of ferroelectric oxide films, focusing on single-crystal film of PbTiO_3_ on single-crystal Nb:SrTiO_3_ substrate. We would like to provide additional information to further support its epitaxy and single-crystal character by electron back-scattered diffraction (EBSD) and rocking curve analysis. Figure 1a presents a typical EBSD band contrast map of PbTiO_3_ film in a relatively large area, and the uniform color of the inverse pole figure (IPF) map in the Z direction (IPF Z in Fig. 1b) demonstrates that PbTiO_3_ film is a single crystal. Furthermore, the fullwidth at half maxima (FWHM) of the rocking curve (Fig. 1c) scanned around the (001) diffraction peak is only 0.028°, indicating a high-quality epitaxy of PbTiO_3_ film on the substrates.
