Hi,
... also, in GaN forexample again we have 2 Ga and 2 N in the unit cell, right, so how could I mention the basis I have for Ga as an example, because I have only mentioned the ghost atom with a negative sign of atomic number? All in all, how could I have a real Ga and a ghost Ga basis? ...
Well, you could cheat the atomic species. Just say you have Ga1 and Ga2, both sharing the same pseudo and basis (as real Ga); Ga1 gets +Z and Ga2 -Z . How about that ? ... ;) Bye, bye, Roberto
