الوصف: In order to study the change of the electronic states from the charge-transfer(CT) type metal to the Mott-Hubbard(MH) one, X-ray photoemission spectra are measured on the NiAs-type (Co 1- x V x ) 0.91 S ( x ≤ 0.50) and V 0.91 S. The asymmetry parameter α for S 2 s and 2 p core level spectra decrease with increasing x . This result indicates that the local density of states of S atoms at the Fermi level decreases as x increases; the system changes from the CT-type metal to the MH-one with x . The change in V 2 p line shape with x suggests the possibility of the considerable hybridization between V 3 d and S 3 p in (Co 1- x V x ) 0.91 S at lower x region. This feature would be related to the appearance of the extra peak at binding energy E B = 2–3 eV in the valence band X-ray photoemission spectra.
