研究了多晶Tl填充方钴矿TlxCo 4Sb 12（x=0，0.05，0.10，0.15，0.20和0.25）在室温至750 K范围内的高温热电性能。所有样品均表现出负的Seebeck系数。电阻率，塞贝克系数的绝对值，和晶格热导率被发现随Tl含量的增加而降低。Tl0.25Co4Sb12具有最好的TE性能，在600 K时无量纲优值ZT最大值为0.90。(C)2010年美国物理学会。[doi 10.1063/1.3430739]
The high temperature thermoelectric (TE) properties of polycrystalline Tl-filled skutterudites TlxCo4Sb12 (x=0, 0.05, 0.10, 0.15, 0.20, and 0.25) were examined from room temperature to 750 K. All samples exhibited negative Seebeck coefficients. The electrical resistivity, absolute values of the Seebeck coefficient, and the lattice thermal conductivity were found to decrease with increasing Tl content. Tl0.25Co4Sb12 exhibited the best TE performance; the maximum value for the dimensionless figure of merit ZT was 0.90 at 600 K. (C) 2010 American Institute of Physics. [doi: 10.1063/1.3430739]
