Thermoelectric performance of the filled-skutterudite LaFe4Sb12 and CeFe4Sb12

Thermoelectric properties of metallic antiperovskites AXD3 (A=Ge, Sn, Pb, Al, Zn, Ga; X=N, C; D=Ca, Fe, Co)

“…Secondly, only pseudo-eigenvalues are available in the DFT approximation. [48] Therefore, it is important to note that besides its advantages, DFT has its limitations. [49,50] We also calculated the Seebeck coefficient of these materials against chemical potential at 300, 600 and 900 K temperature for better understanding of its behavior, as presented in Figs.…”

First-principle studies of the ternary palladates CaPd3O4 and SrPd3O4

“…Mathematically the Seebeck coefficient can be expressed as S = V / T , where V is the TE voltage and T is the temperature difference [45,46]. The Seebeck coefficient (S) gives a useful picture of the electronic structure of the material around the Fermi level [47]. As the Seebeck coefficient is moderate there should be a single-type carrier, and these low carriers lead to the semiconductor nature [48], which confirms the semiconducting nature of these materials.…”

Thermoelectric Properties of LazFe4-xCoxSb12 Skutterudites

“…Much research has examined the extent of the thermal conductivity reduction at a specific temperature in the filled skutterudite by controlling filler atoms, filling fraction, atomic displacement and frequency. [11][12][13][14][15][16][17][18][19][20][21][22] In this study, p-type La-filled skutterudites were synthesized, and thermoelectric and transport properties were examined. In addition, the charge compen-sation was performed by substituting Fe for Co and by varying the filling fraction of La.…”
