LMAXMIX and LDA+U??
Posted: Sun Mar 09, 2008 11:18 pm
Hi,
I have a smalle question about this parameter with regard to it's use when doing a bandstructure calculation on an LDA+U system.
The manual tell's that this parameter should be set to 4 or 6 for respectively d and f shells...the problem is I use the +U on a p shell only(Germanium, only way to get a bandgab in the DOS). I found that also 1 and 2 are acceptable values but what I could not figure out is the relation between the values and orbitals.
normally s->l=0, p->l=1, d->l=2, f->l=3
What does LMAXMIX mean when it is 1 and 2? is 3 also a possible value?
thx
Danny
