sym = kwant.TranslationalSymmetry(latt.vec((-1,0))) sym.add_site_family(latt.sublattices[0], other_vectors=[(-1, 2)]) sym.add_site_family(latt.sublattices[1], other_vectors=[(-1, 2)]) lead = kwant.Builder(sym)
Making a hole on the scatter reign is ok. I did the same procedure for lead to make hole on it but at the end there isn't any hole on the leads (it is like a rectangular). That is very kind of you if let me know what is the problem? how can I make it?
You haven't made the translational symmetry in the leads big enough. Think about how big the unit cell of the leads is, and how big the hole you are trying to make is. Joe
