Based on the density functional theory, we demonstrate that Aun (n=4–7) can have stabilized configurations such as like-ring and three dimensional (3D) clusters. Au4 adopt the square geometry with the D4h space group. The Au6 hexagonal cluster seems to be more stable than all other geometries with a zero magnetic moment. A new 3D Au6 can be retrieved with a slight difference in binding energy compared with the cyclic one.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
