- Abstract
The topological surface state of Bi2Te3 leads to high photoemisson intensity from its Dirac point. This allows us to investigate the effect of larger amounts of deposited Fe than previously achieved for Bi2Se3. The Dirac point is shown to stay intact up to at least a monolayer showing the robustness of the topological state towards disordered magnetic moments. (© 2013 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim) Because magnetic moments lift time reversal symmetry and topological protection, the reaction of topological insulators to deposited magnetic moments is a matter of current debate. The authors contribute to this discussion with the system Fe/Bi2Te3 where spectroscopically favorable conditions allow them to observe the Dirac point even after a full monolayer is deposited.
