[Wien] Seebeck coefficient_Boltztrap

[Fecher, Gerhard]

why do you expect that the Seebeck is symmetric arround zero chemical potential (whatever you assume to be the Zero)
is your density of states symmetric with respect to the middle of the band gap ?

Betreff: [Wien] Seebeck coefficient_Boltztrap

Dear Wien2k users;
I'm using the boltztrap code to study the thermoelectric properties of some semiconducting materials.
I run the process and I got the results. But I have a problem; when I drew the figure that represents the Seebeck coefficient as a function of the chemical potential, I didn't get the curve symmetric around zero chemical potential. I got the curve at the right of the zero chemical potential.
Also I tried to reproduce the examples that are given in the package like Bi2te3, to know if it is happened only with these materials, and I had the same problem.
What could be the mistake that I did in the calculations?
Best regards
Hannan
