Quantitative analysis of vacuum deposited alloy film by Auger electron spectroscopy

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 ...

Characterization of nitrate particulate dry deposition by vacuum-deposited thin film reaction method

Air samples were collected at a highway intersection, coastal location and suburban area in Taichung, Taiwan for the characterization of nitrate containing particulates (NCPs) in dry deposition from October 2002 to February 2003. Sampling was accomplished with a surrogate surface technique in non-raining days. Collecting tapes were precoated with nitron (C20H16N4) in a vacuum evaporator control...

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...
