Dear Shashi,

Here is my nscf.in, nscf.out, epw.in and epw.out files.

I interrupted the calculation of epw because I noticed that the Fermi energy was completely wrong, which led to the final part of the output being truncated.

Dear all, I tried to calculate the Electron phonon coupling matrix of AB-Stacked Bilayer Graphene (have four C atoms). But, I observed a significant discrepancy between the Fermi energy level obtained from EPW calculations and the one derived from the SCF calculations. The Fermi energy level for AB ...
