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…
Interface-Controlled Defect Engineering in TiN/TaN Superlattices for Enhanced Hardness and Fracture Toughness
Zecui Gaoa, Qimin Wang, Julian Buchinger +6
TiNTaN superlattice coatings were designed to investigate how atomic-scale interface chemistry and defect-stabilized TaN layers govern hardness and fracture toughness. Guided by fi…
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…
Impact of O concentration on the thermal stability and decomposition mechanism of (Cr,Al)N compared to (Ti,Al)N thin films
Pauline Kümmerl, Ganesh Kumar Nayak, Felix Leinenbach +6
The composition-dependent thermal stability of (CrAl)(ON) thin films with O concentrations of y = 0, 0.15, and 0.40…
