| 抄録: | Structural, metallurgical, and low-temperature thermoelectric properties have been investigated for Zn_<13+x>Sb_<10> compounds prepared by the gradient freeze and vacuum melt-quench methods at various starting Zn compositions. The Rietveld analysis of the powder x-ray diffraction profiles indicates that the excess Zn occupies mainly the 36f-3 and 36f-4 interstitial sites. It is also revealed that the actual Zn composition and lattice constants have strong correlation with occupation factors of the 36f-3 and 36f-4 sites. The thermoelectric property strongly depends on the actual Zn composition. The enhancement in the electrical resistivity and Seebeck coefficient associated with the β to α structural phase transition is more remarkable for the samples with larger starting Zn composition. On the other hand, the lattice thermal conductivity also exhibits a remarkable increase at the transition temperature, indicating an ordered Zn structure in theα phase. These facts indicate that the occupation of Zn in the two interstitial 36f-3 and 36f-4 sites gives a significant effect on the crystal and electronic structures of the Zn_<13+x>Sb_<10> system. |
