a Cross-sectional TEM image of the VAN thin film C0 and b its corresponding STEM image at low magnification. c Cross-sectional and d plan-view HRTEM images of sample C0. In the HRTEM image of (c), “C” in yellow points out the CeO2 nanopillars and “L” in green points out the La0.7Sr0.3MnO3 (LSMO) matrix. Clearly, those CeO2 nanopillars with a large aspect ratio are vertically aligned and well distributed in the LSMO matrix and the sharp phase boundaries suggest the well separated growth of the two phases. Cross-sectional TEM images of the thin films e–g C1–C3 and h–j L1–L3, showing the microstructures of 3D interconnected CeO2 and LSMO frames embedded within the thin films respectively.
