Combined Auger Electron Spectroscopy and Electron Impact Desorption Studies

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...

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 ...

Directional 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...

Electron-induced KLL Auger electron spectroscopy of Fe, Cu and Ge

KLL Auger spectra excited by electrons with energies in the 30–35 keV range of Fe, Cu and Ge films were measured, using thin free-standing films. It was possible to obtain spectra with an energy resolution of about 1 eV. The observed spectra can not be described satisfactorily by just the multiplet splitting of the final state as calculated for an isolated atom. Additional features, due in part...
