question on transport above surface

[rose]

Hi,
I would wonder how i can investigate transmission pathway or similar characteristic to see the transport above the surface of nano-structures such as benzene. I read somewhere that the transport properties of these structures are above surface of atoms (almost 0.6A above surface for benzene).

I would then suggest that you calculate the current density
