[Pw_forum] band structure

[程迎春]

Dear pwscf users,
        I have a problem about the band structure. When I calculate the band
structure of an kind of semiconductor, I found an inconsistent
problem between using conventional cell and primitive cell. The conventional
cell shows the direct band gap ,while the primitive one shows
indirect band gap. My Question: what kind of band gap of this semiconductor
is. Any suggestion is appreciated.
       Thank you in advance!
