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…
Interplay of electronic structure and atomic ordering on surfaces: Momentum-resolved measurements of Cs atoms adsorbed on a Ag(111) substrate
Hendrik Bentmann, Arne Buchter, Friedrich Reinert
Surface-state mediated interactions between adsorbates on surfaces can be exploited for the fabrication of self-organized nanostructures such as two-dimensional superlattices of ad…
