Umberto Martinez,
Yes, that will be helpful....
... (because, the calculation of Seebeck for semi metals...where you don't have significant BG....itself is tricky...sometimes confusing too..!!)
Besides, can u please tell me that....
1) What is the significance of showing a range of ZT values which are too low....?? (can it be used to justify the metallic behaviour ??!!!)
2) And the Interpretation of a Larger or, smaller Peltier Coeff.
Thanks__
