      abstract     = {The electronic structure of the clean and stoichiometric
                      GaN(10¯10) cleavage surface is investigated in a
                      comprehensive angle-resolved photoelectron spectroscopy
                      study. A clear distinction between surface and bulk related
                      features allows us to measure the dispersions of the
                      occupied surface state band from the N dangling bonds as
                      well as of the uppermost bulk valence bands and to extract
                      the effective hole masses directly with high precision. This
                      is performed along various directions in k∥ space
                      providing a detailed picture of the electronic band
                      dispersion. The obtained results show three separated bulk
                      bands without indications of a crossing of these bands as
                      commonly predicted in theoretical works. Moreover, from the
                      observed Fermi-level pinning we determine the position of
                      the minimum of the empty Ga-derived surface state band,
                      which is found deep within the fundamental band gap at
                      ∼2.3 eV above the valence band maximum.},
