Post Electron-phonon coupling and doping
Dear all,

I am trying to calculate the effect of doping on the electron phonon coupling coefficient (lambda). I want to make sure that the technique I am thinking of is correct:

1- First change the number of electrons in the crystal.fmt file and obtain the new Fermi energy.
2- Re-run calculations for lambda using the new value of EF. No need to run the first epw1 calculations (the lengthy calculations of the el-ph matrices) since these do not include the Fermi energy. Is this right?

Dear Elio,

That is correct in the approximation that the effect of doping is only to rigidly shift the Fermi level.
