[Pw_forum] problem with k-points

[Sanjeev Kumar Gupta]

Respected sir,

i am sanjeev gupta, from india, working DFT calculation via Quantum-Espresso-3.1.1. I have doubts with k-ponits,
1)How we choose k-points for diiferent system?
2)Is possible fermi energy negative for noble nitrides?
3)Is neccessary same k-points for scf and nscf cycle or phX,phL and phG.?


with regards
sanjeev gupta
