Surface Studied with Auger Electron Spectroscopy
We present an Auger electron spectroscopy (AES) study of the adsorption of nitric oxide (NO) on a dean Si(100)2 × 1 surface at 300 and 550 K. Accurate measurements reveal wall resolved fine structure at Auger Si L2.3 w transitions at 62 and 83 eV. These peaks can be attributed to Si-O and Si-N bonds. Furthermore, it is argued that the broadening in the SiLi2,~W Auger transition at 83 eV at 300 ...
متن کاملThe Effects of Surface Roughness on Auger Electron Spectroscopy
The contribution of surface asperities to AES emission yields is discussed in terms of topography analysis. The methods allowing the distribution of heights, slopes, curvatures and other angular functions to be determined are presented here.
متن کاملAnalysis of the NiCo2O4 spinel surface with Auger and X-ray photoelectron spectroscopy
Nickel cobaltite, NiCo2O4, has been synthesized by sol–gel and thermal decomposition techniques and the surface composition studied with Auger (AES) and X-ray photoelectron spectroscopies (XPS). The asintroduced samples are near-stoichiometric, although samples fabricated by thermal decomposition tend to be oxygen-defi cient by approximately 25% of the predicted spinel concentration. Nickel 2p ...
متن کاملOxide Surface Analysis of Nickel Based Chromium Alloys with the Aid of Auger Electron Spectroscopy
Auger Electron Spectroscopy (AES) has been used to study the surface compositions of three types of nickel based chromium alloys. These alloys are IN600, IN601 and C22. AES analysis indicated the presence of chromium and oxygen on their surfaces. The formation of this chromium oxide surface layer, 3 nm thick, provides excellent corrosion resistance. For alloy C22, no molybdenum was indicated on...
متن کاملHigh Resolution Auger Spectroscopy in Metallurgy: an Advanced Technique for Surface Analysis
A brief review of the high spatial resolution Auger electron spectroscopy (HRAES) and its usage in metallurgy is presented. A combination of HRAES and X-ray photoelectron spectroscopy makes a powerful combination to resolve a large number of problems encountered in metallurgy. Several selected examples of such problems studied in the authors’ laboratory are presented: influence of surface activ...
