Abstract
AbstractIn‐plane heterostructures of graphene and hexagonal boron nitride (h‐BN) exhibit exceptional properties, which are highly sensitive to the structure of the alternating domains. Nevertheless, achieving accurate control over their structural properties, while keeping a high perfection at the graphene‐h‐BN boundaries, still remains a challenge. Here, the growth of lateral heterostructures of graphene and h‐BN on Rh(110) surfaces is reported. The choice of the 2D material, grown firstly, determines the structural properties of the whole heterostructure layer, allowing to have control over the rotational order of the domains. The atomic‐scale observation of the boundaries demonstrates a perfect lateral matching. In‐plane heterostructures floating over an oxygen layer have been successfully obtained, enabling to observe intervalley scattering processes in graphene regions. The high tuning capabilities of these heterostructures, along with their good structural quality, even around the boundaries, suggest their usage as test beds for fundamental studies aiming at the development of novel nanomaterials with tailored properties.
