Anisotropic effect of warping on the lifetime broadening of topological surface states in angle-resolved photoemission from BiTe
J. Sánchez-Barriga, M. R. Scholz, E. Golias +5
We analyze the strong hexagonal warping of the Dirac cone of BiTe by angle-resolved photoemission. Along , the dispersion deviates from a line…
Elemental Topological Insulator with a Tunable Fermi Level: Strained α-Sn on InSb(001)
A. Barfuss, L. Dudy, M. R. Scholz +16
We report on the epitaxial fabrication and electronic properties of a topological phase in strained α-Sn on InSb. The topological surface state forms in the presence of an unusual…
Reversal of the circular dichroism in the angle-resolved photoemission from Bi2Te3
M. R. Scholz, J. Sánchez-Barriga, J. Braun +11
The helical Dirac fermions at the surface of topological insulators show a strong circular dichroism which has been explained as being due to either the initial-state spin angular…
Probing two topological surface bands of Sb2Te3 by spin-polarized photoemission spectroscopy
C. Pauly, G. Bihlmayer, M. Liebmann +9
Using high resolution spin- and angle-resolved photoemission spectroscopy, we map the electronic structure and spin texture of the surface states of the topological insulator Sb2Te…
Tolerance of topological surface states towards magnetic moments: Fe on Bi2Te3 and Bi2Se3
M. R. Scholz, J. Sánchez-Barriga, D. Marchenko +4
Topological insulators(1-8) are a novel form of matter which features metallic surface states with quasirelativistic dispersion similar to graphene(9). Unlike graphene, the locking…
High spin polarization and circular dichroism of topological surface states on Bi2Te3
M. R. Scholz, J. Sánchez-Barriga, D. Marchenko +4
Topological insulators have been successfully identified by spin-resolved photoemission but the spin polarization remained low (~20%). We show for Bi2Te3 that the in-gap surface st…
