Abstract

We have investigated the impact of F-doing on CeO_1-xF_xBiS₂ in terms of the electronic-structural parameters of Anderson's impurity-model analysis. It was recently reported using Ce L₃-edge x-ray absorption spectroscopy (XAS) that CeOBiS₂ falls in the Ce valence fluctuation regime and the F-doping drives the system into the Kondo regime. The Ce L₃- edge XAS spectra with the various F-doping levels can be reproduced by adjusting the transfer integral in the Anderson's impurity model. The present analysis indicates that the F-doping to the system corresponds to the decrease of the Ce-Bi transfer integral.
