Confinement of charge carriers in bilayer graphene

Abstract

In this thesis we investigate the fundamental properties of electronic transport in bilayer graphene. We do this by confining electrons to narrow constrictions and small islands. Our key result is the fabrication and measurement of nanoscale devices that permit confinement with electric fields in bilayer graphene for the first time on a substrate. We observed the quantum mechanical nature of electrical transport in a narrow constriction. Moreover we measured single electrons tunnelling onto a small island in the bilayer graphene. The platform we developed paves the way for further investigations into the fundamentals of electronic transport in (bilayer) graphene.
