Electronic band structure changes across the antiferromagnetic phase transition of exfoliated MnPS probed by -ARPES
Jeff Strasdas, Benjamin Pestka, Milosz Rybak +17
Exfoliated magnetic 2D materials enable versatile tuning of magnetization, e.g., by gating or providing proximity-induced exchange interaction. However, their electronic band struc…
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…
Strong and Weak Three-Dimensional Topological Insulators Probed by Surface Science Methods
Markus Morgenstern, Christian Pauly, Jens Kellner +12
We review the contributions of surface science methods to discover and improve 3D topological insulator materials, while illustrating with examples from our own work. In particular…
Exploring the subsurface atomic structure of the epitaxially grown phase change material GeSbTe
J. Kellner, G. Bihlmayer, V. L. Deringer +7
Scanning tunneling microscopy (STM) and spectroscopy (STS) in combination with density functional theory (DFT) calculations are employed to study the surface and subsurface propert…
Mapping the band structure of GeSbTe phase change alloys around the Fermi level
Jens Kellner, Gustav Bihlmayer, Marcus Liebmann +16
Phase change alloys are used for non-volatile random access memories exploiting the conductivity contrast between amorphous and metastable, crystalline phase. However, this contras…
$\mbox{Bi}_{1}\mbox{Te}_{1}$: a dual topological insulator
Markus Eschbach, Martin Lanius, Chengwang Niu +15
A combined theoretical and experimental study reveals evidence for the dual topological insulating character of the stoichiometric natural superlattice phase $\mathrm{Bi_{1}Te_{1}}…
