Quantum Transport and Shot Noise in Graphene-Boron Nitride Heterostructures

This thesis presents experiments on the electronic transport properties of mesoscopic graphene samples at low temperature. Due to the residue free encapsulation in hexagonal boron nitride, the mean free path of charge carriers is in the order of the geometric sample dimensions. High frequency shot noise was measured in parallel to the conductance under various experimental conditions, including proximity induced superconductivity and high magnetic fields.
