It is shown that RBa(2)Cu(3)O(7-X) single crystals may be used as reference samples for the quantitative analysis of RBa(2)Cu(3)O(7-X) thin films by SNMS. RSF-values for Y and Cu (relative to Ba) determined for ceramic RBa(2)Cu(3)O(7-X) samples are higher than those for single crystals. This difference may be caused by Ba segregation on grain boundaries. The depth profile analysis of YSZ/Al(2)O(3) samples was performed by DBM using a Ni grid to prevent sample charging. The reproducibility of analysis was better than 10%.
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.
