Coulomb dominated cavities in bilayer graphene
Electrostatic confinement in bilayer graphene van der Waals heterostructures provides a versatile platform for studying electronic transport in bilayer graphene nanostructures. We study bilayer graphene cavities which we interpret in terms of quantum dots that are strongly coupled to the leads. We i...

| description | Electrostatic confinement in bilayer graphene van der Waals heterostructures provides a versatile platform for studying electronic transport in bilayer graphene nanostructures. We study bilayer graphene cavities which we interpret in terms of quantum dots that are strongly coupled to the leads. We investigate how the transport signatures evolve when changing the size of the cavity for both electron and hole occupation. In addition, we analyze the interplay of single and double quantum dot physics in the regime where transport through the quantum dot system is almost pinched off. |
