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…
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…
Relocation of the topological surface state of BiSe beneath the surface by Ag intercalation
M. Ye, S. V. Eremeev, K. Kuroda +16
We studied the Ag-intercalated 3D topological insulator BiSe by scanning tunneling microscopy/spectroscopy and angle-resolved photoemission spectroscopy, combined with…
Experimental verification of PbBiTe as a 3D topological insulator
K. Kuroda, H. Miyahara, M. Ye +15
The first experimental evidence is presented of the topological insulator state in PbBiTe. A single surface Dirac cone is observed by angle-resolved photoemission spect…
