Add metal directly on graphene layer

[Bobby]

I am wondering how to add metal as a interconnect wire (so it looks like a top gate without dielectric) directly on the top of a graphene layer (not on the sides) in ATK.

I know how to add metal from this example http://quantumwise.com/documents/tutorials/latest/BenzeneSET/index.html/chap.SET.html

But when there is no dielectric between metal and graphene, how much distance should I give between them (metal and graphene)? 1.42A ?

Thanks in advance.
