Hello,
I am modeling a graphene lattice that is rectangular in shape.
graphene = kwant.lattice.general([(1, 0), (sin_30, os_30)],
[(0, 0), (0, 1 / sqrt(3))])
When you attach the leads (with symmetry parallel to the rectangle edges),
extra lattice sites get added. I want to avoid this and my thinking is that you
define a seperate lattice for the leads, such that it is a unit cell
translatable like a square lattice, which in this case would be something like:
lattice_lead = kwant.lattice.general([(1, 0), (0, 2*cos_30)],
[(0, 0), (0, l(1 /
sqrt(3))),(0.5,((1/sqrt(3))+(tan_30*0.5))),(0.5,((2/sqrt(3))+(tan_30*0.5)))])
My question is firstly, is this the way to go about it? And secondly, how does
this interplay with the sublattices and thier hoppings?
