[Pw_forum] reconstruction

[Prasenjit Ghosh]

Dear Ali,

Usually when you speak of simulating a nanowire, because of the periodic
boundary conditions, you simulate an infinite one. If the nanowire is
aligned along Z axis, which seems to be your case,  then you have
periodicity along the Z-direction. Therefore you need to  have enough vacuum
along the x & y direction so that the periodic images should not interact.

Prasenjit.
