Derivation of an Improved Semi-empirical Expression for the Re-ionisation Background in Low Energy Ion Scattering Spectra
H. R. Koslowski, Ch. Linsmeier
Low energy ion scattering is a technique to detect the energy of ions which are scattered from a surface. For noble gas ions, it is predominantly sensitive to the topmost surface l…

Temporally resolved LEIS measurements of Cr segregation after preferential sputtering of WCrY alloy
Hans Rudolf Koslowski, Janina Schmitz, Christian Linsmeier
The dynamic behaviour of thermally driven segregation of Cr to the surface of WCrY smart alloy is studied with low energy ion scattering (LEIS). Sputtering the WCrY sample with 500…

Segregation and Preferential Sputtering of Cr in WCrY Smart Alloy
Hans Rudolf Koslowski, Janina Schmitz, Christian Linsmeier
The temperature driven segregation of Cr to the surface of the tungsten-based WCrY alloy is analysed with low energy ion scattering of He+ ions with an energy of 1 keV in the tempe…
