| 英文摘要 | films were deposited on Si (100) substrates by RF-magnetron sputtering technique. The influence of Fe doping on the local structure of films was investigated by X-ray absorption spectroscopy (XAS) at Fe K-edge and L-edge. For the films with , Fe ions dissolve into and substitute for sites with a mixed-valence state () of Fe ions. However, a secondary phase of Fe metal clusters is formed in the films with . The qualitative analyses of Fe-K edge extended X-ray absorption fine structure (EXAFS) reveal that the Fe-O bond length shortens and the corresponding Debye-Waller factor () increases with the increase of Fe concentration, indicating the relaxation of oxygen environment of Fe ions upon substitution. The anomalously large structural disorder and very short Fe-O distance are also observed in the films with high Fe concentration. Linear combination fittings at Fe L-edge further confirm the coexistence of and with a ratio of () for the film with . However, a significant fraction () of the Fe metal clusters is found in the film with . |
