Abstract

The growth of graphene has been carried out on cube-textured (100) oriented Cu (CTO-Cu) foils using chemical vapor deposition (CVD). Well-aligned triangular grains self-assembled on CTO-Cu during CVD heating in flowing hydrogen. The nucleation of triangular graphene grains has been confirmed. This demonstrates that the shape and possible alignment of the graphene grains can potentially be tuned by changing the properties of the substrate, which should ultimately lead to improved electrical properties of the graphene. This type of graphene nucleation and alignment is novel and has not been observed in previous studies on other copper foil samples. The growth of graphene has been carried out on cube-textured (100) oriented Cu (CTO-Cu) foils using chemical vapor deposition (CVD). Well-aligned triangles self-assembled on CTO-Cu during CVD. The nucleation of triangular graphene grains on CTO-Cu has been demonstrated. The triangles on the CTO-Cu are predominantly in the shape of right triangles. In some cases, equilateral triangles are also observed. (Figure 2a and 2b)
