“…Accordingly, straight lines with slope +3 in the Wagner plot correspond to atoms with the same initial states. We have to point out that although this simplified picture is valid for core levels, in the case of ZnO, the participation of 3d states in the Auger transition could be ambiguous, as it hybridizes with about a 10% of the valence band . Due to this restricted hybridization we are confident that the previous equations for the Wagner plot are valid for the interpretation of the ZnO/graphene/Cu system.…”

“…6,d) contain two components. The first one (O1) at 530.2 eV corresponds to the lattice oxygen in the ZnO phase, while the high-energy component (O2) at 531.2 eV is assigned to the different oxygen-containing species on the zinc oxide surface, which include hydroxy groups and different forms of chemisorbed oxygen [2528]. No changes were detected in the Zn 2p XPS spectrum of ZnO/SiC nanocomposites compared with the similar spectrum of ZnO.…”

“…20,21 From x-ray photoelectron spectra the admixture of Zn 3d states in the O 2p band has been determined to be about 9% indicating a small covalent contribution to bonding. 22 The band dispersion has been investigated via angle-resolved photoelectron spectroscopy along a few highsymmetry directions. 23,24 The measurements reveal a strong dispersion of the upper valence bands and a smaller dispersion of the Zn 3d levels.…”

“…This effect is further enhanced in ZnO due to the underestimation of the repulsion between the Zn 3d and conduction band levels, 21 which leads to a significant hybridization of the O 2p and Zn 3d levels 21 and eventually to an overestimation of covalency. 25 Schröer et al have performed an analysis of the wave functions obtained from self-consistent pseudopotential calculations and determined a contribution of 20%-30% of the Zn 3d orbitals to the levels in the upper valence band 26 ͑to be compared with the experimental estimate of 9% covalency cited above 22 ͒. For zinc oxide the band gap calculated with LDA or GGA is about 0.7-0.9 eV, which is just about 25% of the experimental value ͑3.4 eV͒.…”
