How to obtain cumulative mean free path transport property

[guodonglin]

Dear EPW developers,

I am writing to ask about the possibility of obtaining cumulative mean free path transport properties using the EPW code. In the literature, I often see figures showing cumulative mean free path transport properties (as shown in the attached image), which are also calculated using EPW. I would like to consult on how to modify the code to obtain cumulative electrical conductivity and Seebeck coefficient as functions of the mean free path.

Could you please provide some guidance on this matter? Any suggestions on which parts of the code to modify or which output files to use would be greatly appreciated.

Best regards,
Donglin Guo
