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?
