Hexagonal boron nitride (hBN) is the supporting substrate of choice fortwo-dimensional material devices because it is atomically flat and chemicallyinert. However, due to the small size of mechanically exfoliated hBN flakes,electronic structure studies of 2D materials supported by hBN usingangle-resolved photoemission spectroscopy (ARPES) are challenging. Here weinvestigate the electronic band structure of a Bernal-stacked bilayer graphenesheet on a hexagonal boron nitride (BLG/hBN) flake using nanospot ARPES(nanoARPES). By fitting high-resolution energy vs. momentum electronic bandspectra, we extract the tight-binding parameters for BLG on hBN. In addition,we reveal spatial variations of the alignment angle between BLG and hBNlattices via inhomogeneity of the electronic bands near the Fermi level. Weconfirmed these findings by scanning tunneling microscopy measurements obtainedon the same device. Our results from spatially resolved nanoARPES measurementsof BLG/hBN heterostructures are instrumental for understanding experiments thatutilize spatially averaging techniques such as electronic transport and opticalspectroscopy.
