Title: Is the experimental conductance of graphene comparable with ATK results?
Post by: jinylee on May 5, 2015, 05:48

Dear ATK team

I wonder if the conductance of graphene calculated in ATK results can be comparable with an experimental value.

I already know most of the measured conductance of graphene reflects incoherent scattering, thus it can not comparable with ATK results.

But, how about the case in the paper "Phase-coherent transport in graphene quantum billards" (Science, 2007, 317, 1530-1533). I think under this measurement condition, the comparison between experiment and calculation can make sense.

I wonder this comparision can be possible.

Attached is the paper titled "Phase-coherent transport in graphene quantum billards"

Thank you in advance.

That is a really interesting scientific question, but I am not quite sure what the answer is. It may even be that you would get different answers depending on who you ask :)

If the measurement is really done under conditions that can be accurately modeled by theory, I would expect ATK to be the weapon of choice.
