Sponsored by Park SystemsApr 29 2021 It is possible to generate long-range wavelength ordering known as Moiré superlattice periodicity by stacking two-dimensional (2D) materials within each other’s van der Waals interaction distance. When this process is applied to graphene on hexagonal boron nitride (hBN), this effect would appear on the uppermost layer of graphene, causing graphene’s energy bandgap to open. 1,2,3  Regulating lattice orientation between graphene and boron nitride can facilitate variation in the Moiré periodicity s wavelength, effectively tuning the graphene energy bandgap. The energy bandgap range will, in turn, affect graphene’s performance and device functionalities. 4 Researchers will therefore benefit from a simple means of deciphering Moiré shape and periodicity, particularly when designing 2D graphene/BN-like heterostructured devices and materials.
