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.}, cin = {PGI-5}, ddc = {530}, cid = {I:(DE-Juel1)PGI-5-20110106}, pnm = {141 - Controlling Electron Charge-Based Phenomena (POF3-141)}, pid = {G:(DE-HGF)POF3-141}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000468209300003}, doi = {10.1103/PhysRevB.99.195306}, url = {https://juser.fz-juelich.de/record/862831}, }
