Abstract

Here we present measurements on p-n junctions in encapsulated graphene revealing several sets of magnetoconductance oscillations originating from quasiclassical snake states and edge state Aharonov-Bohm interferences. Even though some of these oscillations have already been observed in suspended and encapsulated devices including different geometries, their identification remained challenging as ...
