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.
