摘要：

Hexagonal graphene flakes: Equiangular hexagon-shaped graphene domains are synthesized by methane chemical vapor deposition on copper surface in a controlled manner. These graphene domains possess either a armchair or zigzag edge, and are formed via a nucleation and growth mechanism. The left image is a typical AFM image of one graphene flake, and the right image indicates the armchair or zigzag edge of hexagonal graphene.
