Auger Electron Spectroscopy of Free Argon Clusters
Auger electrm specm and Auger yields of free argon clusm in the I\I('Zp) excitation regime are reported. The Auger yield specua show chmcmistic changes as a function of cluster size. The results indicafe that the Auger yield signal originates primarily i%om the surface of the clusm. The results are compared to bulk-sensitive experimental techniques, such as tMal elecucm yields my), zero kinetic...
متن کاملSurface 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.

15 صفحه اولDirectional Auger Electron Spectroscopy — Possibilities, Limitations and Proposal of Improvements
Physical foundations of directional auger electron spectroscopy (DAES) and calculation of DAES profiles in single scattering cluster approach are presented. Limitations of this method (application only to investigation of the crystalline structure of homogeneous samples) is shown and explained as the result of participation of inelastically scattered electrons in the Auger signal generation. To...
