Figure 10. (A) Schematic illustration of the preparation process of Pd/a-SrRuO₃ hybrid films by PLD; (B) HRTEM planar view of the Pd/a-SrRuO₃ sample. This figure is quoted with permission^[106]; (C) Atomic force microscopy image of the surface morphology of the SrRuO₃ thin film; (D) Oxygen tracer diffusion coefficient. This figure is quoted with permission^[107]; (E) Cross-sectional HAADF-STEM image of (Sr_0.6Ba_0.4)MnO₃ thin film, with FFT highlights of the perovskite and hexagonal phases. This figure is quoted with permission^[108]; (F) High-magnification cross-sectional HAADF-STEM image of Ba_0.6Sr_0.4MnO₃ thin film; (G) Low-magnification cross-sectional HAADF-STEM image of Ba_0.6Sr_0.4MnO₃ thin film. This figure is quoted with permission^[109]; (H) Mechanism A: Conversion of B-SCO to HSrCoO₃ through a quasi-nucleophilic addition process; (I) Mechanism B: Oxidation of the underlying B-SCO by active oxygen. This figure is quoted with permission^[110]. PLD: Pulsed laser deposition; HRTEM: high-resolution transmission electron microscopy; HAADF-STEM: high-angle annular dark-field scanning transmission electron microscopy; FFT: fast Fourier transform; B-SCO: brownmillerite SrCoO_2.5.
