LDA+U
Posted: Sun Sep 16, 2018 12:47 am
Hi,
I am trying to get the right band gap for GaN and Ga2O3 by correcting the interaction of p orbital of
N and O, however, I only see a trivial change of band gap for changes within the range of U-J= 0 to 8 eV,
LDAU = .TRUE.
LDAUTYPE = 2
LDAUL = -1 1 # Ga N
LDAUU = 0 0->8
LDAUJ = 0 0
LMAXMIX=4
LDAUPRINT=2
what can be the reason ?
Thank you for your help
