Identifying band structure changes of FePS3 across the antiferromagnetic phase transition
Benjamin Pestka, Jeff Strasdas, Gustav Bihlmayer +16
Magnetic 2D materials enable novel tuning options of magnetism. As an example, the van der Waals material FePS3, a zigzag-type intralayer antiferromagnet, exhibits very strong magn…
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…
Electronic Structure of the Dark Surface of the Weak Topological Insulator Bi14Rh3I9
Christian Pauly, Bertold Rasche, Klaus Koepernik +6
The compound Bi14Rh3I9 consists of ionic stacks of intermetallic [(Bi4Rh)3I]2+ and insulating [Bi2I8]2- layers and has been identified to be a weak topological insulator. Scanning…
