Interband spin-orbit coupling between anti-parallel spin states in Pb quantum well states
Bartosz Slomski, Gabriel Landolt, Stefan Muff +3
Using spin and angle-resolved photoemission spectroscopy we investigate a momentum region in Pb quantum well states on Si(111) where hybridization between Rashba-split bands alters…
Separating the bulk and surface n- to p-type transition in the topological insulator GeBi(4-x)SbxTe7
Stefan Muff, Fabian von Rohr, Gabriel Landolt +5
We identify the multi-layered compound GeBi4Te7 to be a topological insulator with a freestanding Dirac point, slightly above the valence band maximum, using angle-resolved photoem…
Tuning of the Rashba effect in Pb quantum well states via a variable Schottky barrier
Bartosz Slomski, Gabriel Landolt, Gustav Bihlmayer +2
Spin-orbit interaction (SOI) in low-dimensional systems results in the fascinating property of spin-momentum locking. In a Rashba system the inversion symmetry normal to the plane…
