Dear Nick,

thank you for your reply. I really appreciate your help. Please, say if i
am correct or no.

1) What does k-points implicitly mean in calculations?

            1.1) Periodicity.

2) Is that meaning compatible with your simulation?

             2.1) In the transversal direction i think that no, because i
have one supercell only.

3) In your simulation, what would be the difference between a k-point
simulation and a non k-point simulation?

          3.1) With k-point: For more that one supercell(more that one
junction).
                  Non k-point: For one molecular junction only.

Thank you.

Leone
