Photochromic response of encapsulated oxygen-containing yttrium hydride thin films
Marcos V. Moro, Sigurbjörn M. Aðalsteinsson, Tuan. T. Tran +4
Photochromic oxygencontaining yttriumhydride thin films are synthesized by argonmagnetron sputtering on microscope slides. Some of them are encapsulated with a thin, trans…
Simultaneous assessment of energy, charge state and angular distribution for medium energy ions interacting with ultra-thin self-supporting targets: a time-of-flight approach
R. Holeňák, S. Lohmann, F. Sekula +1
We demonstrate simultaneous measurements of the charge state, energy and angular distribution of keV ions in transmission experiments through self-supporting foils. Using a time-of…
Mn-rich MnSb2Te4: A topological insulator with magnetic gap closing at high Curie temperatures of 45-50 K
S. Wimmer, J. Sánchez-Barriga, P. Küppers +18
Ferromagnetic topological insulators exhibit the quantum anomalous Hall effect that might be used for high precision metrology and edge channel spintronics. In conjunction with sup…
Trajectory-dependent electronic excitations by light and heavy ions around and below the Bohr velocity
Svenja Lohmann, Radek Holeňák, Daniel Primetzhofer
We present experiments demonstrating trajectory-dependent electronic excitations at low ion velocities, where ions are expected to primarily interact with delocalized valence elect…
Unprecedented Severe Atomic Redistribution in Germanium Induced by MeV Self-Irradiation
Tuan T. Tran, Daniel Primetzhofer
We present a pronounced unprecedented surface modification of a crystalline Ge layer under heavy ion irradiation with a Ge ion beam at high energy of 2.5 MeV. Under the irradiation…
In-situ Nanoscale Characterization of Composition and Structure during Formation of Ultrathin Nickel Silicide
Tuan T. Tran, Christian Lavoie, Zhen Zhang +1
We characterize composition and structure of ultrathin nickel silicide during formation from 3 nm Ni films on Si(100) using in-situ high resolution ion scattering and high resoluti…
Impact of the experimental approach on the observed electronic energy loss for light keV ions in thin self-supporting films
Barbara Bruckner, Philipp M. Wolf, Peter Bauer +1
Energy spectra of backscattered and transmitted ions with primary energies of 50 keV and 100 keV interacting with self-supporting foils were recorded with a Time-of-Flight Medium-E…
Contrast modes in a 3D ion transmission approach at keV energies
R. Holeňák, S. Lohmann, D. Primetzhofer
We present options for visualizing contrast maps in 3D ion transmission experiments. Simultaneous measurement of angular distributions and flight time of ions transmitted through s…
Correlating chemical composition and optical properties of photochromic rare-earth oxy-hydrides using ion beam analysis
S. M. Aðalsteinsson, M. V. Moro, D. Moldarev +3
We relate the photochromic response of rare-earth oxy-hydride thin films (YHO, NdHO, GdHO and DyHO) synthesized by reactive magnetron sputtering to chemical composition. Depth prof…
Synthesis and characterization of photochromic yttrium oxyhydride grown by reactive -beam evaporation
K. Kantre, M. V. Moro, D. Moldarev +2
We report on controlled growth of photochromic yttrium oxyhydride thin films monitored by composition depth profiling. Films were grown by reactive -beam ev…
Assessing electron emission induced by pulsed ion beams: a time-of-flight approach
Svenja Lohmann, Anna Niggas, Vincent Charnay +2
We present a method to measure the kinetic energy of electrons emitted upon ion impact via their time-of-flight. Pulsed beams of H, D, He and Ne ions with…
Tailoring magnetic order via atomically stacking 3d/5d electrons
Ke Huang, Liang Wu, Maoyu Wang +18
The ability to tune magnetic orders, such as magnetic anisotropy and topological spin texture, is desired in order to achieve high-performance spintronic devices. A recent strategy…
