X-Ray Absorption Fine Structure (Xafs) Studies Of Cobalt Silicide Thin Films
MRS Proceedings, 1998ABSTRACTCobalt silicide thin films, prepared on Si(100) wafers, have been studied by X-ray absorption near edge structures (XANES) at the Si K-, L2,3 and Co K-edges utilizing both total electron (TEY) and fluorescence yield (FLY) detection as well as extended X-ray absorption fine structure (EXAFS) at the Co K-edge.

Abstract X-Ray absorption fine structure (XAFS) studies were performed for cobalt(II) bromo complexes prepared for the ratio Br/Co from 0.0 to 4.0 and for their oxidized complexes with ozone in acetic acid solvent. The multivariate curve resolution method indicates the existence of two kinds of chemical species both before and after the ...

Metal impurities in the carbon nanotubes and carbon nanofibers play an important role in understanding their physical and chemical properties. We apply the Ni $K$-edge x-ray absorption fine structure analyses to the local electronic and geometric structures around embedded Ni impurities used as catalysts in a carbon nanofiber in combination with ...
