High-resolution transmission electron micrographs and selected area electron diffraction patterns. (a) Cross-sectional high-resolution transmission electron micrograph of the EuTiO₃/SrTiO₃(001) interface along the SrTiO₃[$\bar{1}00$] zone axis. The insets show the high-resolution micrographs of the EuTiO₃ films and SrTiO₃ substrate taken in focus, respectively. Selected area electron diffraction patterns of (b) EuTiO₃ and (c) SrTiO₃, respectively.
