Chemical and Localization Effects in Auger Lineshapes of Transition Metal Compounds.
Abstract
The compounds MXn(X=C, N, O) display sequential changes in the C-KLL Auger spectra and these changes in the C-KLL Auger spectra and these changes correlate with the density -of-states (DOS), the relative proportions of ionic, covalent and metallic bonding, and screening and localization of the Auger holes. In this work we quantitatively interpreted the C-KLL lineshape of TiC, using previously described techniques. We further investigated the X-Kll lineshape changes as the number of 3d electrons increases across the rows of the transition metals, and as the nonmetalloid atom changes from C to N to 0. The effects of sample nonstoichiometry were also examined. Originator supplied keywords include: Auger electron spectroscopy, Localization, Carbides, and Screening.
