Abstract:Sulphur X-ray fluorescent K bands, X-ray absorption near the edge structure (K-XANES), and emission L2,3 bands are obtained in semiconducting A'BiS, (A' = Li, Na, K, Rb) sulphides. The electronic structure of the [BiS6l9-cluster, which is a fragment of the investigated compounds, is calculated by the self-consistent field X,-scattered wave (X,-SW) method. On the basis of a joint analysis of X-ray emission spectra the fine structure, the XANES data and the results of X,-SW calculation the energy band structure … 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.
