文摘

We report the magnetic, electrical, and thermoelectric properties of SnCCo₃, where good thermoelectric performance [figure of merit ZT 0.035(2), 258 K] and strong electron correlation (Kadowaki鈥揥oods ratio R_KW 4a₀) are observed. The thermoelectric properties of ACCo₃ (A = Al, Ga, Ge) and SnCM₃ (M = Mn, Fe) were also investigated for comparison. As a result, the ZT value of SnCCo₃ is the largest among all of those samples, which is mainly attributed to the large Seebeck coefficient caused by the strong electron correlation and low carrier density. Moreover, the ZT value can be effectively enhanced by proper chemical doping in SnCCo₃.
