Equiangular Hexagon‐Shape‐Controlled Synthesis of Graphene on Copper Surface

Abstract

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 armchair or zigzag edge, and are formed via nucleation and growth mechanism. Left image is a typical AFM image of one graphene flake, and right image indicates the armchair or zigzag edge of hexagonal graphene.
