Structures of SinHm clusters in neutral, positive and double positive charge states have been calculated by nonconventional tight-binding method and molecular dynamics. An influence of the charge state and the termination by hydrogen of dangling bonds on cluster structures those are obtained as a result of chemical vapor precipitation in silane, is considered for the first time. Fully hydrogenated clusters have tetrahedral branched structures. Other isomers have forms of closed circles.
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.
