Two-dimensional hexagonal boron nitride (h-BN) single crystals with various shapes have been synthesized by chemical vapor deposition over the past several years. Here, we report the formation of three-leaf dart (3LD)-shaped single crystals of h-BN on a Cu foil by atmospheric-pressure chemical vapor deposition. The leaves of the 3LD-shaped h-BN are as long as 18 μm, and their edges are smooth armchair on one side and stepped armchair on the other. Careful analysis revealed that surface oxygen...[Show more]
