Patterning Graphene with Zigzag Edges by Self‐Aligned Anisotropic Etching

A top-down approach for controlled tailoring of graphene nanostructures with zigzag edges is presented. It consists of two key steps: artificial defect patterning and hydrogen-plasma etching. With this approach, various graphene nanostructures with sub-10 nm features and identical zigzag edges are reliably achieved. This approach shows great promise for making future graphene devices or circuits. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
