Web7 apr. 2024 · For quantification of XPS data as well as for calibration of nanoscale dimensions employing electron beam attenuation, it is imperative to have reliable values of the electron inelastic mean free path (IMFP) at one's disposal. The work by Shinotsuka, Tanuma, Powell and Penn 5-12 is the most important point of reference in this connection. WebXPS is a powerful measurement technique because it not only shows what elements are present, but also what other elements they are bonded to. The technique can be used in line profiling of the elemental composition across the surface, or in depth profiling when paired with ion-beam etching. http://www.xpsfitting.com/2013/11/inelastic-mean-free-path-calculations.html jgm宇都宮ゴルフクラブ口コミ

Following, the IMFP is employed to calculate the effective attenuation length (EAL), the mean escape depth (MED) and the information depth (ID). Besides, one can utilize the IMFP to make matrix corrections for the relative sensitivity factor in quantitative surface analysis. Moreover, the IMFP is an important parameter in Monte Carlo simulations of photoelectron transport in matter. http://aranne5.bgu.ac.il/others/GivonAlon3.pdf
