mBJ was made to be good for band gaps only, such that there is<br>
no reason to expect better results than PBE for other properties<br>
like EFG. So, in a publication this would justify to consider the EFG<br>
from PBE instead of mBJ.<br>

Subject: [Wien] PBE vs mBJ<div><div class="h5"><br>
<br>
Dear Sirs,<br>
<br>
I’m interested in simulating the EFG at impurity sites in wide band gap semiconductors and their impact in the density of states.<br>
I’ve been using the PBE functional to optimize the structure but then I used to mBJ potential to get a better band gap and density of states.<br>
However, the EFG values change considerably from PBE to mBJ, being the PBE results the ones closer to the experimental values.<br>
Therefore, I would like to ask if I can consider the EFG values from PBE and the density of states from mBJ or if this is not a good approach.<br>
<br>
Thank you very much.<br>
<br>
Best regards,<br>
Marcelo<br>
