Resistivity of Pb using BTE

[Vahid]

Dear EPW Community,

In the Hands-on session on resistivity and mobility with EPW, the resistivity of Pb is calculated using the Ziman formula. Are there any reasons for not using BTE instead of Ziman formula given that Ziman formula is an approximation to BTE?

Thank you,
Vahid

Dear Vahid,

For metal, one typically look at the conductivity or resistivity but not mobility.

Indeed you can compute the conductivity using the BTE instead of the Ziman formula in EPW.

In the development version on GitLab, look for the new input variable 'assume_metal' to do that.

Best wishes,
Samuel.
