Description: Find the direct and indirect gaps and the valence and conduction Kohn-Sham states that form it and select to compute their self-energy due to electron-phonon coupling.
| Mind: Available as of VASP 6.5.0 |
This tag additionally activates the reporting of the value of the band-gap renormalization to the standard output, the OUTCAR file
$ grep -A7 'KS-QP gap (meV)' OUTCAR
and the vaspout.h5 file under
$ h5ls -r vaspout.h5 | grep gap_renorm /results/electron_phonon/electrons/self_energy_1/direct_gap_renorm /results/electron_phonon/electrons/self_energy_1/fundamental_gap_renorm`
This output is reported once for each electron-phonon accumulator.
If instead, the computation of the self-energy for a particular set of states is desired, those can be manually specified using a combination of ELPH_SELFEN_KPTS, ELPH_SELFEN_IKPT, ELPH_SELFEN_BAND_START and ELPH_SELFEN_BAND_STOP.
