Ep. Mikheeva et al., MODELING THE PHOTOELECTRON-SPECTRA OF THE VALENCE O2P-BAND OF ZINC-OXIDE BY THE XA-SCATTERED WAVE METHOD, Journal of structural chemistry, 38(5), 1997, pp. 732-741
The photoelectron spectra (PES) of the valence O2p-band of zinc oxide
are modeled by X alpha-scattered wave cluster calculations in a wide r
ange of incident quantum energies h nu (from 30 to 150 eV and 1253.6 e
V). For the Zn10O10 cluster, the calculated intensities of PES reprodu
ce well the specific features of the experimental spectra. It is shown
that Zn3d-electrons participate in covalent binding of zinc and oxyge
n. The admixture of the Zn3d-states in the hybrid orbitals of the vale
nce band is approximate to 7%.
