Figure 2: Sample size effect on the electrical and thermal transport properties.

From: Colossal Seebeck effect enhanced by quasi-ballistic phonons dragging massive electrons in FeSb2

Figure 2

(a) Temperature dependence of electrical resistivity. (b,c) Temperature dependence of Seebeck coefficient and thermal conductivity. Both properties show a striking size dependence in the high-purity single crystals. ρ and S for the low-purity polycrystalline sample are plotted as grey lines in a,b, respectively.
