[Pw_forum] Calculating Work function of a nanoribbon

I was calculating the workfunction of a graphene nano-ribbon using the
example WorkFCT as a template. I also read the post here:
My question is when I calculate the WF for a nanoribbon I have vacuum along
two directions and the ribbon is infinite in one (say Y dirn).
In this case, I can calculate the macroscopic average of the potential
along x or z, and both of them should give me the energy level of the
vacuum in that space. Shouldn't these levels be the same?
I did the calculations along the z direction and also tried along x to
verify, but I get different potentials along x and z.
Can someone please clarify?
