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…
Topological surface state under graphene for two-dimensional spintronics in air
A. Varykhalov, D. Marchenko, M. R. Scholz +3
Spin currents which allow for a dissipationless transport of information can be generated by electric fields in semiconductor heterostructures in the presence of a Rashba-type spin…
