We have found that three types of atomic clusters exist as basic structural units: star, flattened hexagon and decagon with an edge-length of 0.65 nm. These three types of units are linked to each other by sharing edges or inter-penetrating, with adjacent star clusters overlapping each other. The respective structural models of these structural units are proposed from the HAADF STEM images.||URI:||https://hdl.handle.net/10356/139106||ISSN:||0167-577X||DOI:||10.1016/j.matlet.2018.09.002||Rights:||© 2018 Elsevier B.V.
