Fig. 1: IMO–AZO–mica heteroepitaxial structure.

a Schematic of the IMO/AZO/mica heterostructure. b Typical θ–2θ scan of the heterostructure. c Φ-scans for IMO{400}, AZO {101}, and muscovite {202} diffraction peaks. d Rocking curves for IMO (222) and AZO (002) diffraction peaks. e Cross-sectional TEM image of the IMO/AZO/mica interface and fast Fourier transform images for the IMO, AZO, and mica.
