Abstract
We provide a semiclassical description of the electronic transport through graphene junctions in the quantum Hall regime. A semiclassical approximation for the conductance is derived in terms of the various snakelike trajectories at the interface of the junction. For a symmetric (ambipolar) configuration, the general result can be recovered by means of a simple scattering approach, providing a very transparent qualitative description of the problem under study. Consequences of our findings for the understanding of recent experiments are discussed.
