bilayer graphene nanoribbon and two-probe system

[gump]

Hi,everybody,do anyone has the script to create bilayer graphene nanoribbon? and can we use
the bilayer graphene nanoribbon to build two-probe system and calculate transport properties
with ATK? I will appreciate if anybody give me the clue or some reference papers.

A script for generating graphene nanoribbon has been demonstrated here:

You may try to modify it by adding more one graphene layer to obtain the bilayer graphene nanoribbon. For the atomic positions in this second graphene layer,  only the z-coordinations of atoms are different to those in the first graphene layer if we consider a bilayer graphene with ABAB stacking.

and can we use the bilayer graphene nanoribbon to build two-probe system and calculate transport properties with ATK?

Of course, you can do it as usual.

Zh,Thank you very much for your kind  assistance.
