Crystals with two-dimensional lattice structure, such as graphene, can be obtained from bulk crystals, such as graphite, by peeling off atomically-thin layers held in place by weak interlayer van der Waals attraction. Stacking the resulting isolated layers onto a substrate or back together allows to design so-called van der Waals heterostructures. In this procedure, introducing a finite twist angle between layers leads to a structural beating pattern, known as a moiré structure, characterized by an intermediate length scale between atomic and mesoscopic systems. This dissertation addresses how the moiré pattern impacts the electronic properties in three different graphene-based twisted-layer systems of increasing complexity. Show more
