Since the quantum Hall effect of hybrid graphene is impeded by its usual silicon dioxide substrate, the objective of this project is to stack hybrid graphene onto isoelectronic few-atom thick hexagonal boron nitride (hBN) lattices, constructing a van der Waals heterostructure. The electronic properties measurement of the heterostructure at low temperature and high magnetic field up to 9T yielded improved quality of quantum Hall resistance data. However, the visibility of graphene is compromised with the new BN substrate, the second part of this project is to investigate spectroscopic methods to inverse image graphite using a home-built Raman microscope.
