The topological surface state forms in the presence of an unusual band order not based on direct spin-orbit coupling, as shown in density functional and GW slab-layer calculations. Angle-resolved photoemission including spin detection probes experimentally how the topological spin-polarized state emerges from the second bulk valence band. Moreover, we demonstrate the precise control of the Fermi level by dopants.","authors_text":"A. Barfuss, A. Bostwick, A. Fleszar, C. Blumenstein, D. Wortmann, E. Rotenberg, G. Bihlmayer, G.
