Cross-section high-resolution TEM images of (a) and (b) Eu123 both deposited on at 785 °C. orientations are marked as arrows in (a) and (b).
-contrast image of sample A. Two white arrows indicate the positions of the and the interfaces, respectively.
(a) -contrast image of sample B. A trapezoidal shaped Eu123 grain with -axis orientation is seen and the four corners of the trapezoid are marked using four white arrows. orientations are marked in different areas of the film; (b) the intensity profile along the Eu123 layer immediately above the STO substrate. The layer is indicated by a black arrow in (a).
(a) A high-resolution -contrast image of a interfacial area in sample A. A white line is drawn along ; (b) intensity profile along the white line in (a); (c) a high-resolution -contrast image of a interfacial area in sample B. A white line is drawn along ; (d) the intensity profile along the white line in (c). The interface position is marked as white arrow in (a) and (c), and black arrow in (b) and (d). Two scale bars with the same width are placed at the substrate area and the epilayer immediately above the substrate in (b) and (d).
