Charge-State Dependence of Electronic Excitations in keV Ions Transmitted Through Solids Probed by Ion-Photon Coincidence Measurements
Kevin Vomschee, Radek Holeňák, Svenja Lohmann +2
Investigating the electronic excitations caused by light keV ions in matter contributes to a better understanding of materials modification such as space weathering or plasma-wall…
Quantitative Analysis of Composition and Contamination of Atomically Thin Materials by Recoil-Projectile Coincidence in Ion Transmission
Carolin Frank, Kevin Vomschee, Tuan Thien Tran +6
Surface contamination strongly affects the intrinsic properties of nanoscale materials, making its reliable identification and quantification crucial for both accurate experimental…
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…
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…
