Determination of the Spacing Between Hydrogen-Intercalated Quasi-Free-Standing Monolayer Graphene and 6H-SiC(0001) Using Total-Reflection High-Energy Positron Diffraction
Matthias Dodenhöft, Izumi Mochizuki, Ken Wada +5
We have investigated the structure of hydrogen-intercalated quasi-free-standing monolayer graphene (QFMLG) grown on 6H-SiC(0001) by employing total-reflection high-energy positron…
Imaging low-energy positron beams in real-time with unprecedented resolution
Michael Berghold, Vassily Vadimovitch Burwitz, Lucian Mathes +2
Particle beams focused to micrometer-sized spots play a crucial role in forefront research using low-energy positrons. Their expedient and wide application, however, requires highl…
Novel Data Analysis Tool for the Evaluation of Coincidence Doppler Broadening Spectra of the Positron-Electron Annihilation Line
Leon Chryssos, Christoph Hugenschmidt
Coincidence Doppler Broadening Spectroscopy (CDBS) of the 511 keV annihilation line reveals the elemental signature at the annihilation site in matter. For this reason, CDBS enable…
Total-Reflection High-Energy Positron Diffractometer at NEPOMUC -- Instrumentation, Simulation and First Measurements
Matthias Dodenhöft, Sebastian Vohburger, Christoph Hugenschmidt
We report the instrumentation of a new positron diffractometer that is connected to the high-intensity positron source NEPOMUC. Crucial elements for the adaption of the positron be…
Momentum Density Spectroscopy of Pd: Comparison of 2D-ACAR and Compton Scattering Using a New 1D-to-2D Reconstruction Method
Josef Ketels, David Billington, Stephen B. Dugdale +2
Two-dimensional angular correlation of annihilation radiation (2D-ACAR) and Compton scattering are both powerful techniques to investigate the bulk electronic structure of crystall…
Fermi-Surface Modeling of Light-Rare-Earth Hexaborides with 2D-ACAR Spectroscopy
Josef Ketels, Michael Leitner, Peter Böni +6
Two dimensional angular correlation of the positron annihilation radiation (2D-ACAR) spectra are measured for along high symmetry directions and compared with firs…
