Figure 1. (A) Schematic illustration of Zn_1-xCd_xS preparation; (B) a typical TEM image of Zn_0.5Cd_0.5S; (C) HAADF-STEM and corresponding elemental mappings of Zn_0.5Cd_0.5S; HR-TEM images of (D) WZ phase and ZB phase in a single crystal, (E) and (F) FFT patterns in the selected areas in (D); (G) ZB phase crystal and (H) WZ phase crystal; (I) HR-TEM image with the labeling of twin boundaries and elemental mappings at the atomic scale (inset). TEM: Transmission electron microscopy; HAADF-STEM: high-angle annular dark-field scanning transmission electron microscopy; HR-TEM: high-resolution transmission electron microscopy; WZ: wurtzite; ZB: zinc-blende; FFT: fast Fourier transform.
