Dear QE users
Sir I am doing some calculations on FeS2 which is a diamagnetic
semiconductor of expt band gap of 0.9eV and i got this band structure
attached to this mail aand I would like to ask if it is possible for some
band from valence band to cross fermi level for a semiconductor material as
seen in the figure in whjch band at the edges crosses the fermi level and
if it is correct is there any explanation for this.

Thanks
