Kurzfassung englisch:
We investigate substrate and edge effects in graphene nanodevices
of realistic size (up to 100 nm) using a tight-binding approach.
We consider the periodic moire potential induced by placing graphene nanostructures
on hexagonal boron nitride. In particular, we are interested in the
Hofstadter butterfly emerging in the density of states when applying a
perpendicular magnetic field. To assess the importance of edge effects, we calculate the eigenstates of finite-sized flakes with rough edges.
Our results compare well with current experimental results.
