Dear Zhida Song
I'm putting the Pw_forum mailing list in cc as that would be a
more appropriate address where to submit queries about PWscf. Please
sign your future posts with your affiliation.
coming to your question.... think what is the difference between
a localized basis set code and plane wave one ?
what would be the results of an empty cell by flpo ? empty !
what would be the result of a pw code ? the 3-D free electron
band structure projected on the z axis..
which one is correct ?
so what is missing in your friend's band structure that Pwscf
correctly gives ?
hope this helps, best,
stefano
