We have measured thermoelectric properties of Ta₂PdX₆ (X = S, Se) around room temperature using single crystal samples. We find that the power factor of Ta₂PdX₆ is relatively high from middle-low to room temperatures, and notably Ta₂PdSe₆ shows the largest power factor among thermoelectric materials with an electrical conductivity of 10⁻² Ω cm at 300 K. Ta₂PdS₆ will be a possible candidate for a Peltier cooling material if the lattice thermal conductivity is reduced by chemical substitution.

异结构硒化物Ta2PdS6和Ta2PdSe6的室温热电性质

我们使用单晶样品测量了室温下Ta ₂ PdX ₆（X = S，Se）的热电性能。我们发现，Ta的功率因数₂ PDX ₆是比较高的，从中间低温至室温的温度下，且特别是钽₂ PDSE ₆示出了具有为10的导电性的热电材料中的最大功率因数^-2 Ω厘米在300K如果通过化学取代降低晶格热导率，Ta ₂ PdS ₆将成为珀尔帖冷却材料的候选材料。
