From Wiki and this paper: Cusack, N.; Kendall, P. (1958). "The Absolute Scale of Thermoelectric Power at High Temperature". Proceedings of the Physical Society. 72 (5): 898. What mechanism is related to this phenomenon? Is it phonon drag or spin or something else?

  • $\begingroup$ I’ve read this page before and the anomalous Seebeck of Cu Ag Au is different. They’re positive at all the temperature. No sign change occurs. $\endgroup$ – Wenjie Zhang Mar 22 '19 at 16:21
  • $\begingroup$ But it does for Li, as noted in that answer. Go read the cited paper. $\endgroup$ – Jon Custer Mar 22 '19 at 16:29
  • $\begingroup$ You mean this cited paper journals.aps.org/prl/abstract/10.1103/PhysRevLett.112.196603 $\endgroup$ – Wenjie Zhang Mar 23 '19 at 1:31
  • $\begingroup$ In this paper, there are three sources of Lithium's Seebeck measured. Only one changes its sign, and its tendency doesn't match with the other two. This only source is a paper published in 1924. In this 1924 paper, many other alkali were measured and have sign reverse too, which is not the case from modern experiments. $\endgroup$ – Wenjie Zhang Mar 27 '19 at 2:56
