Solving the disordered structure of -CuSe using the three-dimensional difference pair distribution function
Nikolaj Roth, Bo B. Iversen
High-performing thermoelectric materials such as ZnSb and clathrates have atomic disorder as the root to their favorable properties. This makes it extremely difficult to un…
Model-free reconstruction of magnetic correlations in frustrated magnets
Nikolaj Roth, Andrew F. May, Feng Ye +2
Frustrated magnetic systems exhibit extraordinary physical properties but quantification of their magnetic correlations poses a serious challenge to experiment and theory. Current…
Nanoscale Surface Dynamics of BiTe(111): Observation of a Prominent Surface Acoustic Wave and the Role of van der Waals Interactions
Anton Tamtögl, Davide Campi, Martin Bremholm +8
We present a combined experimental and theoretical study of the surface vibrational modes of the topological insulator BiTe. Using high-resolution helium-3 spin-echo spectr…
A Helium-Surface Interaction Potential of BiTe(111) from Ultrahigh-Resolution Spin-Echo Measurements
Anton Tamtögl, Michael Pusterhofer, Martin Bremholm +7
We have determined an atom-surface interaction potential for the HeBiTe(111) system by analysing ultrahigh resolution measurements of selective adsorption resonances. Th…
