Dear Weiyuan,
at the moment, there is no ready-to-use function to do that in kwant. We are right now planning a feature set for kwant 2.0, where this will be definitely included (you can have a look at our kwant-devel mailing list if you want to keep updated).
Best,
Michael

Dear authors, Can we plot the band structure of a system with periodical bondary conditions in y direction? For example, it is easy for us to plot the band structure of a graphene nanoribbon, however, for a bulk graphene(infinite in y direction) can we plot the band structure using kwant? Best wishes, Weiyuan Tong
