Cheianov, Vadim V. and Falko, Vladimir (2006) Selective transmission of Dirac electrons and ballistic magnetoresistance of n-p junctions in graphene. Physical review b, 74 (4). -. ISSN 1098-0121Full text not available from this repository.
We show that an electrostatically created n-p junction separating the electron and hole gas regions in a graphene monolayer transmits only those quasiparticles that approach it almost perpendicularly to the n-p interface. Such a selective transmission of carriers by a single n-p junction would manifest itself in nonlocal magnetoresistance effect in arrays of such junctions and determines the unusual Fano factor in the current noise universal for the n-p junctions in graphene.
