Figure 3. Synthesis of 2D materials by CVD. (A) Schematic diagram of the CVD method. (B-D) Schematic diagram and TEM images of graphene/hBN heterostructures. Here, carbon atoms are represented by blue spheres, boron is shown in yellow, and nitrogen is in purple[71]. (E-G) Synthesis of 2D Fe single-crystal nanoflakes by space-confined CVD[77]. 2D: 2-dimensional; CVD: chemical vapor deposition; TEM: transmission electron microscopy.
