Sputtering of iron, chromium and tungsten by energetic deuterium ion bombardment
Sputtering of the pure materials iron (Fe), chromium (Cr) and tungsten (W) due to energetic deuterium (D) ion bombardment was investigated. These materials are important constituents of reduced-activation ferritic-martensitic steels. Sputtering yields were measured as a function of the D ion energy from 60 to 2000eV/D. The obtained data can be well reproduced by a semi-empirical formula suggested by Bohdansky, and the corresponding fitting parameters are provided. It is confirmed that analytical formulae suggested by Eckstein and Yamamura agree satisfactorily with these experimental data. By comparison with results from the binary-collision-approximation-based calculation codes SDTrimSP and SRIM it is found that SRIM has some limitations in simulating sputter yield close to the threshold whereas SDTrimSP results show good agreement with measured data in the investigated energy range.
