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…
Charge state dynamics of keV ions in solids
Radek HoleÅák, 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…
Long-Range Magnetic Order in Structurally Embedded Mesospin Metamaterials
Christina Vantaraki, Oier Bikondoa, MatÃas P. Grassi +11
Engineered assemblies of interacting magnetic elements-magnetic metamaterials-provide a powerful route to tailor collective magnetic order and dynamics. By structuring matter at th…
Rainbow Scattering from Graphene
Carolin Frank, Kevin Vomschee, Radek HoleÅák +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…
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…
