Compositional mapping and HAADF images of AuTe2Se4/3. a The SEM image of AuTe2Se4/3 and the EDS mapping images of Au (golden), Se (green), and Te (violet) in AuTe2Se4/3. The scale bar here represents 2 μm. b The elemental ratio of Au, Te, and Se obtained from the EDS mapping. The two kinds of atomic distances (red and blue color) are estimated along c [1–39], f [00–1], i [−10−3], and l [−100] zone axes, respectively. The SAED images are taken along d [1–39], g [00–1], j [−10−3], and m [−100] zone axes, respectively. The HAADF images show atomic distributions of Au, Te, and Se along e [1–39], h [00–1], k [−10−3], and n [−100] zone axes in real space, respectively. The scale bars here represent 2 nm. The Au, Te, and Se atoms are superimposed on the spots in n, as the structural analyses (see the text)
