Because the leads need to be translationally invariant if you want a very large distance between defects then your unit cell in the leads needs to be correspondingly large. If you post a code example of what your problem is specifically we may be able to help more. Happy Kwanting, Joe P.S. sorry for the double reply; I forgot to send to the mailing list also
