[Pw_forum] Single Cell vs Super-Cell

[mohsen modaresi]

I have the same question about bandstructure in big unit cells:

 I want to calculate band structructure of a big unit cell but i get some
parallel line . My computing resources are limited and  i can increse one of
the "ecut","ether" , "number of K-point in the scf and band structure
calculation" "self consistent accuracy". What is your suggestion?

thanks
