Measurement of the electrical, thermal, and structural properties of palladium sulfide (PdS) has been conducted in order to investigate its thermoelectric performance. A tetragonal structure with the space group 4/ for PdS was determined from X-ray diffraction measurement. The obtained power factor of 27 μW cm K at 800 K is the largest value obtained for the transition metal sulfides studied so far. The maximum value of the dimensionless figure of merit is 0.33 at 800 K. These results indicate that binary bulk PdS has promising potential for good thermoelectric performance.
为了研究硫化钯（PdS）的热电性能，对其电学、热学和结构性能进行了测量。通过X射线衍射测量确定了PdS的空间群为4/的四方结构。在800K时获得的27μW cm K的功率因子是迄今为止所研究的过渡金属硫化物中获得的最大值。在800K时，无量纲品质因数的最大值为0.33。这些结果表明，二元块状PdS具有良好的热电性能潜力。
