[Wien] band gap problem

[M.Y.Wu]

Dear Wienuser,

I got a question related to the band gap. From the ML, I know there is an 
underestimation for the band gap. Does it affect xspec, elnes optic 
simulation? If the material is an insulator or semiconductor from 
experiment, but the calculation get a conductor. Will the xspec, elnes and 
optic simulations from that still be reasonable or totally meaningless?



Best regards,
Mengyue
