Structure characterization of Zn0.6Cd0.4S
(A) HR-HAADF-STEM image of the WZ phase, corresponding FFT (lower inset), and a low magnification STEM image (upper inset).
(B) HR-HAADF-STEM image of the ZB phase and corresponding low magnification STEM image (inset).
(C) SAED pattern over a large area for Zn0.6Cd0.4S.
(D–F) corresponding EDS elemental maps of zone 1 in (B) indicated by the white dashed box: Cd (red), Zn (green), and S (blue).
(G) Enlarged HR-HAADF-STEM image in (B) together with the ZB crystal model.
(H) Atomic resolution HAADF-STEM image of zone 2 in (B) with quantitative scattered intensities per Cd/Zn column and corresponding histogram of the normalized scattered intensities of the Cd/Zn atomic columns.
