Electronic interaction of slow hydrogen and helium ions in the nickel-silicon system
Tuan Thien Tran, Lukas Jablonka, Barbara Bruckner +6
Electronic stopping cross sections (SCS) of nickel, silicon and nickel-silicon alloys for protons and helium (He) ions are studied in the regime of medium and low energy ion scatte…
Electronic Stopping of Slow Protons in Oxides: Scaling Properties
D. Roth, B. Bruckner, G. Undeutsch +10
Electronic stopping of slow protons in ZnO, VO2 (metal and semiconductor phases), HfO2, and Ta2O5 was investigated experimentally. As a comparison of the resulting stopping cross s…
Free-running Sn precipitates: an efficient phase separation mechanism for metastable GeSn epilayers
Heiko Groiss, Martin Glaser, Magdalena Schatzl +5
We report on the temperature stability of pseudomorphic GeSn films grown by molecular beam epitaxy on Ge(001) substrates. Both the growth temperature-dependence and the influence o…
Electronic Stopping of Slow Protons in Transition and Rare Earth Metals: Breakdown of the Free Electron Gas Concept
D. Roth, B. Bruckner, M. V. Moro +8
The electronic stopping cross sections (SCS) of Ta and Gd for slow protons have been investigated experimentally. The data are compared to the results for Pt and Au to learn how el…
Electronic energy loss processes for slow H and He ions in metals and insulators: new insights
Dominik Goebl, Dietmar Roth, Peter Bauer
Electronic stopping of H and He ions in metals and insulators is analyzed at velocities below 0.2 atomic units, i.e. below 1 keV for H and below 4 keV for He. In metals, stopping o…
Quasi-resonant neutralization of He+ ions at a germanium surface
D. Goebl, D. Roth, D. Primetzhofer +4
When low-energy He ions are scattered from a Ge surface, the fraction of positive ions exhibits characteristic oscillations as a function of ion energy. These oscillations are caus…
