Electron linewidth

Post by weihua-xiao »

Dear all,
I use the hands-on example of diamonds in EPW, the electron linewidth of diamonds is calculated using epw2.in. There is only electron linewidth with band2, 3, 4. I want to get all band’s electron linewidth, how should I modify epw2.in.
Best wishes

Dear weihua-xiao:

Are you referring to epw2.in in the directory of EPW/examples/diamond/epw ?

I will answer to your question by assuming that you are referring to epw2.in in the directory of EPW/examples/diamond/epw .

Code: Select all

fsthick     = 1.36056981 ! eV
With the input above, the 2nd to 4th bands are considered; please find ibndmin and ibndmax in epw2.out
If you remove or comment out the line including fsthick, you can obtain the electron linewidth for all bands.

Regarding fsthick, please check the documentation page at https://docs.epw-code.org/doc/Inputs.html#fsthick .

Sincerely,

H. Lee
