      abstract     = {The magnitude of electron spin polarization in
                      topologically protected surface states is an important
                      parameter with respect to spintronics applications. In order
                      to analyze the warped spin texture in Bi2Te3 thin films, we
                      combine angle- and spin-resolved photoemission experiments
                      with theoretical ab initio calculations. We find an in-plane
                      spin polarization of up to $∼45\%$ in the topologically
                      protected Dirac cone states near the Fermi level. The Fermi
                      surface of the Dirac cone state is warped and shows an
                      out-of-plane spin polarization of $∼15\%.$ These findings
                      are in quantitative agreement with dedicated simulations
                      which find electron density of the Dirac cone delocalized
                      over the first quintuple layer with spin reversal occurring
                      in the surface atomic layer.},
