Spatial Control of Charge Doping in n-Type Topological Insulators
Kazuyuki Sakamoto, Hirotaka Ishikawa, Takashi Wake +17
Spatially controlling the Fermi level of topological insulators and keeping its electronic states stable are indispensable processes to put this material into practical use for sem…
The fate of -wave spin polarization in helimagnets with Rashba spin-orbit coupling
Erik Wegner Hodt, Hendrik Bentmann, Jacob Linder
It has recently been realized that magnetic systems with coplanar magnetic order that are invariant under the combined operation of time-reversal and translation with half a unit c…
Barrier and finite size effects on the extension of topological surface-states into magnetic insulators
Eirik Holm Fyhn, Hendrik Bentmann, Jacob Linder
The interplay between magnetic and topological order can give rise to phenomena such as the quantum anomalous Hall effect. The extension of topological surface states into magnetic…
Systematics of electronic and magnetic properties in the transition metal doped SbTe quantum anomalous Hall platform
M F. Islam, C. M. Canali, A. Pertsova +19
The quantum anomalous Hall effect (QAHE) has recently been reported to emerge in magnetically-doped topological insulators. Although its general phenomenology is well established,…
Single Dirac-cone on the Cs-covered topological insulator surface Sb2Te3(0001)
Christoph Seibel, Henriette Maaß, Minoru Ohtaka +6
Using angle-resolved photoelectron spectroscopy we investigate the surface electronic structure of the three-dimensional topological insulator (TI) Sb2Te3(0001). Our data show the…
Direct Observation of Interband Spin-Orbit Coupling in a Two-Dimensional Electron System
Hendrik Bentmann, Samir Abdelouahed, Mattia Mulazzi +2
We report the direct observation of interband spin-orbit (SO) coupling in a two-dimensional (2D) surface electron system, in addition to the anticipated Rashba spin splitting. Usin…
