The topological surface state of Bi 2 Te 3 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 Bi 2 Se 3 . 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.
