| Research Abstract |
This study aimed to search for novel geometric effects in magnetotransport of graphene. We have mainly studied the quantum Hall edge transport along the graphene junctions. We have experimentally investigated the p/n/p junctions of bilayer graphene and the monolayer-bilayer hetero-junctions of graphene. We have clarified that the full-mixing of parallel edge states and the perfect cancelling of counter-moving edge states occur along the p/n junction of bilayer graphene and the monolayer-bilayer graphene hetero-junction, respectively.
