Role of d electrons in electronic stopping of slow light ions
D. Goebl,D. Roth,Peter Bauer +2 more
TL;DR: In this paper, the electronic stopping power of hydrogen and helium ions in Ag and Pt was determined, and the results were compatible with modeling the conduction band as a free electron gas with an energy-dependent effective number of electrons.

Highly Sensitive Detection of Surface and Intercalated Impurities in Graphene by LEIS
Stanislav Průša,Pavel Procházka,Petr Bábor,Tomáš Šikola,Rik ter Veen,Michael Fartmann,Thomas Grehl,Philipp Brüner,D. Roth,Peter Bauer,HH Hidde Brongersma +10 more
TL;DR: High-resolution LEIS is capable of both checking the purity of graphene surfaces and detecting impurities incorporated into graphene layers or their interfaces, and is a suitable method for monitoring the quality of the whole fabrication process of graphene, including its transfer on various substrates.

Energy loss of low-energy ions in transmission and backscattering experiments
TL;DR: In this article, different effects of nuclear stopping and multiple scattering on the energy spectra for different experimental geometries, i.e., transmission through thin foils and backscattering from thin films, are discussed.

Free-running Sn precipitates: an efficient phase separation mechanism for metastable Ge1-xSnx epilayers.
Heiko Groiss,Martin Glaser,Magdalena Schatzl,Moritz Brehm,Dagmar Gerthsen,D. Roth,Peter Bauer,Friedrich Schäffler +7 more
TL;DR: Time-resolved in-situ annealing experiments in a scanning electron microscope reveal the crucial role of liquid Sn precipitates in this phase separation process that makes phase separation of metastable GeSn layers particularly efficient at rather low temperatures.
Electronic interaction of slow hydrogen and helium ions with nickel-silicon systems
Tuan Thien Tran,Lukas Jablonka,Barbara Bruckner,Barbara Bruckner,Stefanie Rund,D. Roth,Mauricio A. Sortica,Peter Bauer,Peter Bauer,Zhen Zhang,Daniel Primetzhofer +10 more
TL;DR: In this paper, the electronic stopping cross sections (SCSs) of nickel, silicon, and nickel-silicon alloys for protons and helium (He) ions are studied in the regime of medium-and low-energy ion scattering.
