Dear all,

Having gone through the tutorials (up to Plotting Kwant Systems and Data in Various Styles), I am a bit stuck adapting that tutorial and the ones it builds upon to draw a simple zigzag nanoribbon, with the hopping shown and the probability densities shown using circles corresponding to the amplitude (trying to show that the edge state decays into the bulk). The tutorial (and most of the graphene themed tutorials preceding it) always use a circle as the scattering region and then build a quantum dot, add some leads... etc.

Is there a simple example out there showing how I can build a zigzag nanoribbon, just using nearest neighbour hopping, and extract the wavefunction and draw said nanoribbon exactly like the figure at the end of the 2D part of that tutorial.

Thanks, Elmo.
