If we prepare a chain of flourine atoms: F-F-F-F-F-F-F-F-F-F-F-F-F-F-F-F-F-F-F we can construct the band structure shown. I'm using flourine as an example but my question can be generalized: What do we know about the conductivity of a material (such as this 1D chain) when the fermi level lies in the conduction band, ie. above the band gap? I'm also curious how the fermi level would rise and fall if this chain would have been constructed from F- or F + ions. I imagine with the F- ion because all the bands are filled, the structure is most certainly insulating but where would F+ lie?
