From: Large Seebeck effect by charge-mobility engineering

Figure 2

The measured S(T) is compared with calculated values of −ν/μH, that is, the expected Seebeck contribution, Sτ, derived from the mobility gradient, see text. Note that the positive peak developed below 50 K due to the n-type charge carriers can be well reproduced by this ratio. The hatched area indicates the temperature window where two electron-like bands are involved, and these cannot describe the occurrence of the positive S(T) peak.
