Calculated values of Seebeck coefficient are larger than the ones on published data like IEEE TED pp. 423-429 2008. I don’t know the reason. In Si/Ge/Si=2/1/2nm, 300K, 1E17/cm3, then the result is S=865uV/K. But the published data is about a bit under 700uV/K. Could you teach me the reason of difference?
