Seebeck coefficient changes with energy and temperature. I recently thought that when Seebeck coefficients are reported, the energy corresponds to Fermi energy and temperature to room temperature, but this paper got me thinking.(adsbygoogle = window.adsbygoogle || []).push({});

Fig.4 tells us that the Seebeck coefficient at Fermi level is positive. However, Mg2Si is an n-type semiconductor with negative Seebeck coefficient (as Fig.5 confirms). I always thought Seebeck coefficient is calculated at Fermi level, but the two figures suggest otherwise. Would someone please explain where I am mistaken?
