[Pw_forum] Giving shift in K points

[Dimpy Sharma]

Hi Quantum espresso user,

I have to run plane wave calcuation on a periodic stucture to predict the band gap,as my system has 200 atoms (which has 5 unit cells),thus for scf I prefer to choose the k point as
 
K_POINTS automatic 
 1 1 1   0 0 0

where I gave the shift as 0.I would like to ask is it possible to give shift in K_Points for periodic system?as the concept is not clear to me ,can anyone please suggest me some papers or book ?and I would be very greatfull if my question is answered.

Thanks a lot in advance

Dimpy.
