Atomistic Mechanisms of Nonlinear Graphene Growth on Ir Surface

Ping Wu, Huijun Jiang, Wenhua Zhang +3

As a two-dimensional material, graphene can be naturally obtained via epitaxial growth on a suitable substrate. Growth condition optimization usually requires an atomistic level un…

How Graphene Is Cut upon Oxidation?

Zhenyu Li, * Wenhua Zhang, Yi Luo +3

Our first principles calculations reveal that oxidative cut of graphene is realized by forming epoxy and then carbonyl pairs. Direct forming carbonyl pair to tear graphene up from…
