• 論文の詳細を見る

• We have studied the electronic structure of the skutterudite compounds CoSb_3 and Co(Sb_<0.96>Te_<0.04>)_3 by photoemission spectroscopy. Valence-band spectra revealed that a significant amount Sb 5p states are present near the Fermi level and are hybridized with Co 3d states just below it. The spectra are well reproduced by the band-structure calculation, suggesting that the effect of electron correlations is not important. When Te is substituted for Sb and n-type carriers are doped into CoSb_3, the spectra are shifted to higher binding energies as described by the rigid-band model. From this shift and the free-electron model for the conduction and valence bands, we have estimated the band gap of CoSb_3 to be 0.03-0.04eV, consistent with transport measurements. Photoemission spectra of RhSb_3 have also been measured and revealed expected similarities to and differences from those of CoSb_3. Unusual temperature dependence has been observed for the spectra of CoSb_3 and RhSb_3 in the vicinity of the Fermi level.
