      abstract     = {The binary chalcogenides Bi2Te3 and Bi2Se3 are the most
                      widely studied topological insulators. Although the quantum
                      anomalous Hall effect has recently been observed in
                      magnetically doped Sb2Te3, this compound has been studied to
                      a much lesser extent. Here, by using energy-resolved
                      quasiparticle interference mapping, we investigate the
                      scattering events of pristine Sb2Te3 surfaces. We find that,
                      in addition to the Dirac fermions, another strongly
                      spin-polarized surface resonance emerges at higher energies
                      in the unoccupied electronic states. Although the two
                      surface states are of different origin, i.e., topologically
                      protected and trivial, respectively, both show strongly
                      directional scattering properties and absence of
                      backscattering. A comparison with ab initio calculations
                      demonstrates that this is a direct consequence of their
                      spin-momentum–locked spin texture which is found to
                      exhibit an opposite rotational sense for the trivial state
                      and the Dirac state.},
