[Pw_forum] Change Fermi energy in e-ph calculation

[Nicki Frank Hinsche]

Dear all,

is there a possibility to adapt the Fermi energy (obtained by scf) to  
a different value for the
calculation of the Eliashberg function without hardcoding "efermig" in  
elph.f90?
The information on Ef is stored in the binary file "fildvscf",  
therefore cannot be easily manipulated.

The reason for my inquiry is, that I want to enable to calculate the  
Eliashberg function for a "doped"
semiconductor in a sense of rigid band shift. As Ef lies in or at the  
band gap for an undoped semiconductor,
the calculation of the Eliashberg function would make no sense there.

thanks a lot in advance,

Nicki
