Shot noise generated by graphene p–n junctions in the quantum Hall effect regime

The mixing and partitioning suggest that a p–n junction could be used as an electronic beam splitter and the relaxation length is much larger than typical size of mesoscopic devices, encouraging using graphene for electron quantum optics and quantum information processing.
