摘要：

The electronic structure of alpha-Mo2C(0001) has been investigated using photoemission spectroscopy with photon energies in the Mo 4p --> 4d transition threshold region. A broad Fano-like resonance peaked at similar to46 eV is observed in the whole area of the valence band, indicating that the contribution of the Mo 4d orbitals is included in the whole area of the valence band. The Mo 4d contribution to the valence band is found to become more dominant with decreasing binding energy. It is proposed that, though the valence band is mostly composed of Mo 4d-C 2p hybrid states, the band near the Fermi level (0-1 eV) is mostly composed of Mo 4d orbitals. (C) 2004 Elsevier Ltd.
