Hello,
if I understand correctly your question, bands are not aligned with the
Fermi energy at zero. The alignment is consistent with having an average
vanishing electrostatic potential. If you want to have E_f at zero, you
need to get the value of E_f from the output file and translate the
bands up (or down) but the correct amount.
kind regards

Dear all,
I am writing to follow up on the issue I previously reported. I am
still awaiting a response regarding this problem, which persists
consistently. Additionally, I want to mention that this issue occurs
exclusively with GGA+U and not with GGA.

*Subject:* [QE-users] Issue with NiO Band Structure Alignment Using
Hubbard Correction
I want to plot the band structure of AFM NiO with and without the
Hubbard correction. When I added the Hubbard correction, I plotted
E-Efermi, but the valence band maximum is below 0 eV (around -1.8 eV).
I don't know how to correct this to align it with 0 eV.
I attached just the scf.in file (for the nscf file I added just the
nbnd and for band.in I added nband and changed the the k-points to
crystal_b)
Could you please guide me on what might be the issue?
