Abstract: In this paper, the relation between chemical potential and thermoelectric power is investigated by using the linear response theory, possible models of electronic structure, the consequently obtained spectral conductivities, and high-resolution photoemission spectroscopy. We revealed that the effect of temperature dependent chemical potential on thermoelectric power S(T) is negligibly small when its magnitude is limited below 100 μV/K, but becomes nontrivial with increasing S(T). The validity of this argument we proposed on the basis of theoretical calculation was experimentally confirmed using the high-resolution photoemission spectra of the materials possessing a large magnitude in thermoelectric power.
