Abstract: We provide a semiclassical description of the electronic transport throughgraphene n-p junctions in the quantum Hall regime. A semiclassicalapproximation for the conductance is derived in terms of the various snake-liketrajectories at the interface of the junction. For a symmetric ambipolarconfiguration, the general result can be recovered by means of a simplescattering approach, providing a very transparent qualitative description ofthe problem under study. Consequences of our findings for the understanding ofrecent experiments are discussed.
