Hi Sergey,
For what you mentioned in your reply, I prefer to add the hoppings near the
edge because which seems more realistic. But since I am relatively new to
kwant, could you please kindly show me in a concrete way or just lead me to
a concrete example in kwant tutorial (at the moment I did not find such an
example yet) ? Much appreciated for your help.
Thank you a lot.
Best,
Kuangyia

Hi, Just take a tutorial example of graphene with random potential noise added, and change the amplitude of random potential to be larger near the edge. You can also add a random correction to hoppings near the edge. Best wishes, Sergey

Hi everyone,
I am not excellent in using kwant. Recently I want to use kwant to model the edge passivation to a ribbon structure (say a graphene ribbon). Can anyone show me how to implement? Thanks a lot.
Best, Kuangyia
