a The oxygen-bridged coordination network. b HAADF-STEM image of the Turing interface (Zn: Fe = 1:3) and GPA analysis of different plane strains. The interface is marked with a white dashed line in the strain graph, and the curve directly below the graph corresponds to the strain value across the interface. c TEM image of the conventional dual-phase interface (Zn: Fe = 1:3) and GPA analysis of different plane strains. The interface is marked with a purple dashed line in the strain graph, and the curve directly below the graph corresponds to the strain value across the interface. d Crystallographic models of the interface before the phase transition and after the phase transition. e Raman spectra for the β-Fe2O3 powder, α-Fe2O3 powder and the unannealed film (β-Fe2O3). f HAADF-STEM images for the unannealed and calcined films for the only iron source (Fe[C5H7O2]3). g Image of a larger view in the dotted box (Supplementary Fig. 28a). h, Image of a larger view in the dotted box (Supplementary Fig. 28b). i GPA analysis of different plane strains for g. The interface is marked with a white dashed line in the strain graph, and the curve directly below the graph corresponds to the strain value across the interface. j GPA analysis of different plane strains for h. The interface has been marked with a white dashed line in the strain graph, and the curve directly below the graph corresponds to the strain value across the interface. k The semi-coherent interface. Scale bars: b, 5 nm; c, 10 nm; f, 5 nm.
