Re: [Kwant] Bilayer material tight-binding in Kwant

Hi Marc,

Working in 2D is just fine in that case. I think it's also easier, so unless you have a special need for 3D, I'd recommend to omit the z-coordinate.

Dear Kwant developers,

If I want to model a bilayer-type structure like bilayer graphene or phosphorene, do I need to work in three dimensions being the perpendicular lattice constant the interlayer spacing? Or can I still work in two-dimensions since these materials are two-dimensional when the material is periodic in the plane?

Thanks in advance for the help!

Kind regards,

Marc
