We report here on a new, straightforward, and effective method for insulating etched and cut Pt/Ir scanning tunneling microscopy (STM) tips for in situ electrochemical studies. The coating was formed by electrophoretic painting and subsequent heating. It covered all but the very end of the tip, which may be attributed to shrinking of the polymer during heating. We have characterized these tips by voltammetric methods, scanning electron microscopy, and by in situ STM imaging.
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.
