a XRD evolution during phase separation from Hf2O1-xN2 intermediate phase. b Detailed XRD pattern showing changes in the Hf2ON2 (222), HfN (111), Hf2ON2 (004), and HfN (200) peaks. c HAADF-STEM image of coherent interface along [110], with composite FFT inset. d Inverse FFT image revealing the spatial distribution of the Hf2ON2 phase and interface contours, which derived from the red solid circles representing the diffraction spots of Hf2ON2. e GPA strain map (εyy) with Hf2ON2 as reference. f High-resolution STEM of HfN/Hf2ON2 interface with simulated image. g HAADF-STEM image along the [111] zone axis. h, i FFT patterns of HfN and Hf2ON2 regions. j, k Enlarged STEM images of regions in (g) with simulated atomic-resolution images of HfN and Hf2ON2, respectively. Source data for the Fig. 3a, b are provided as a Source Data file.
