Abstract:Accelerators are crucial for electroplating in the electronics industry. In this research, the electrochemical behavior of two accelerators, 3-(benzothiazolyl-2-mercapto)-propyl-sulfonic acid sodium salt (ZPS) and bis(3-sulfopropyl) disulfide (SPS), during Cu electrodeposition was analyzed using electrochemical techniques. Meanwhile, the adsorption behavior of the two accelerators on Cu(111) was also studied using molecular dynamics (MD) simulation, which predicts the preferable reaction sites for nucleophilic… Show more
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.
