The study investigates the transport properties of graphene placed on a boron nitride (BN) substrate, focusing on the effects of the BN substrate's moiré potential on graphene's electronic spectrum. The graphene is accurately aligned with the BN substrate to create a superlattice with a short periodicity and weak disorder. The moiré potential leads to significant changes in graphene's electronic spectrum, including the appearance of second-generation Dirac points as peaks in resistivity and a reversal of the Hall effect sign, indicating changes in the effective mass. The quantizing magnetic fields result in Zak-type cloning of third-generation Dirac points, observed as neutrality points in fields where a unit fraction of the flux quantum pierces the superlattice unit cell. The research highlights the potential of graphene superlattices for studying complex quantum systems and demonstrates the controllable modification of electronic spectra in 2D atomic crystals using their crystallographic alignment within van der Waals heterostructures.The study investigates the transport properties of graphene placed on a boron nitride (BN) substrate, focusing on the effects of the BN substrate's moiré potential on graphene's electronic spectrum.
