Rainbow Scattering from Graphene
Carolin Frank, Kevin Vomschee, Radek Holeňák +3
We report the experimental observation of atomic rainbow scattering of 40 keV Xe ions transmitted through self-supporting single-layer graphene using time-of-flight medium ener…
Probing formation and epitaxy of ultrathin Titanium Silicide using low and medium energy ion scattering
Philipp M. Wolf, Eduardo Pitthan, Zhen Zhang +3
Titanium silicide is a key contact material in advanced three-dimensional semiconductor device architectures. Here, we examine the formation of ultrathin Ti-silicide on Si(100) usi…
The Role of 11B4C Interlayers in Enhancing Fe/Si Multilayer Performance for Polarized Neutron Mirrors
Anton Zubayer, Fredrik Eriksson, Martin Falk +15
This study investigates the effects of incorporating 11B4C interlayers into Fe/Si multilayers, with a focus on interface quality, reflectivity, polarization, and magnetic propertie…
Charge state dynamics of keV ions in solids
Radek Holeňák, Kevin Vomschee, Eleni Ntemou +2
Fast dynamic processes between electrons in solids and a foreign atom represent a fundamental challenge for describing interactions in many-body systems and are a prerequisite for…
The influence of geometry and specific electronic and nuclear energy deposition on ion-stimulated desorption from thin self-supporting membranes
Radek Holeňák, Michaela Malatinová, Eleni Ntemou +2
We investigate the dependence of the yield of positive secondary ions created upon impact of primary He, B and Ne ions on geometry and electronic and nuclear energy deposition by t…
Local electronic excitations by slow light ions in tungsten
Evgeniia Ponomareva, Eduardo Pitthan, Radek Holeňák +4
Accurately predicting the electronic energy deposition of ions in materials is an important challenge in both fundamental and applied research. While employing ab initio simulation…
Time-of-flight recoil detection in transmission using pulsed keV ion beams enables sensitive multi-element profiling with high depth resolution
R. Holeňák, S. Lohmann, D. Primetzhofer
The potential of time-of-flight recoil detection in transmission geometry using pulsed keV ion beams for sensitive multi-element profiling of thin membranes and quasi-2D systems is…
