Unoccupied Topological States on Bismuth Chalcogenides
D. Niesner, Th. Fauster, S. V. Eremeev +9
The unoccupied part of the band structure of topological insulators BiTeSe () is studied by angle-resolved two-photon photoemission and density functiona…
Ideal two-dimensional electron systems with a giant Rashba-type spin splitting in real materials: surfaces of bismuth tellurohalides
Sergey V. Eremeev, Ilya A. Nechaev, Yury M. Koroteev +2
Spintronics is aimed at active controlling and manipulating the spin degrees of freedom in semiconductor devices. A promising way to achieve this goal is to make use of the tunable…
Surface and bulk Fermiology and band dispersion in non-centrosymmetric BiTeI
Gabriel Landolt, Sergey V. Eremeev, Yury M. Koroteev +11
BiTeI has a layered and non-centrosymmetric structure where strong spin-orbit interaction leads to a giant spin splitting in the bulk bands. Here we present high-resolution angle-r…
Topological Surface States with Persistent High Spin Polarization across Dirac Point in BiTeSe and BiSeTe
K. Miyamoto, A. Kimura, T. Okuda +9
Helical spin textures with the marked spin polarizations of topological surface states have been firstly unveiled by the state-of-the-art spin- and angle-resolved photoemission spe…
