local current in graphene nanoribbon
« on: March 14, 2011, 17:29 »
As we know, the current flows at the edge of graphene nanoribbon. And the admin once gave a script to calculate the local current of graphene nanoribbon for 2008 version (sorry, I cannot find it now).
May I know why the local current flows both at the edge and in the central area in the VNL tutorial of 2011.2 (attached)? thanks.

I have a feeling this ribbon is too narrow to show the current localization to the edge. I tried one which was twice as wide and got the figure attached (non self-consistent calculation, run in less than 2 minutes on my slow laptop!).
