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…
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…
Kinetics of the photochromic effect in oxygen-containing rare-earth hydrides
Dmitrii Moldarev, Tuan T. Tran, Max Wolff +1
The kinetics of the photochromic reaction of oxygen-containing rare-earth hydrides is commonly described by an exponential function assuming a single-step process. In this paper, w…
Mobility of single vacancies and adatoms in graphene at room temperature
Tuan T. Tran, Per O. Ã . Persson, Ngan Pham +2
We investigate the mobility of structural defects, adatoms, and defect-adatom combinations in self-supporting graphene subjected to keV ion irradiation. In the first scenario, homo…
The influence of geometry and specific electronic and nuclear energy deposition on ion-stimulated desorption from thin self-supporting membranes
Radek HoleÅák, 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…
Magnetic metamaterials by ion-implantation
Christina Vantaraki, Petter Ström, Tuan T. Tran +6
We present a method for the additive fabrication of planar magnetic nanoarrays with minimal surface roughness. Synthesis is accomplished by combining electron-beam lithography, use…
