Webquantitative, destructive and non-destructive depth profiling are discussed with emphasis on sputter depth profiling and on angle resolved XPS and AES. Taking into account preferential sputtering and electron backscattering corrections, an introduction to the mixing-roughness-information depth (MRI) model and its extensions is presented. WebI have carried out XPS depth profiling analysis for Cu-Ni (90/10) alloy immersed in seawater in the absence and presence of inhibitor for a period of 30 days. We have been using Ar+ ions with1.5 ...

X-Ray Photoelectron Spectroscopy XPS Depth Profiling
WebJun 4, 2010 · An XPS depth profile of the same oxide layer was also measured, with somewhat lower sputtering rate than in AES profiling (Fig. 3).The estimated effective thickness agrees with the one determined from the AES profile, it can be seen, however, that the oxide layer is not homogeneous, with a predominant component towards the top … WebIon gun . The ESCALAB QXi XPS Microprobe has two options for rapid, high-resolution depth profiling: the standard EX06 ion gun, which is optimized for monatomic ion sputtering and ion scattering spectroscopy; and the optional monatomic and gas cluster ion source, MAGCIS, which is capable of monatomic ion profiling, cluster ion profiling, and ion … WebXPS depth profiling Experimental arrangement for a depth-profile experiment. Monatomic depth profiling uses an ion beam to etch layers of the surface or surface contamination, revealing subsurface information. … protein carbonylation pumpkin
