a Schematic presentation of STRO perovskite structure. b XRD patterns of STO and STRO. Inset is the expanded region of main peaks. c Refined XRD profile of the STRO. d HRTEM image of STRO, and e the corresponding FFT pattern. f HAADF-STEM and the corresponding elemental mapping images of STRO. Scale bar in d is 2 nm and in f is 20 nm.
