Bilayer Graphene Growth via a Penetration Mechanism
Ping Wu, Xiaofang Zhai, Zhenyu Li +1
From both fundamental and technical points of view, a precise control of the layer number of graphene samples is very important. To reach this goal, atomic scale mechanisms of mult…
Orientation Sensitive Nonlinear Growth of Graphene: A Geometry-determined Epitaxial Growth Mechanism
Huijun Jiang, Ping Wu, Zhonghuai Hou +2
Although the corresponding carbon-metal interactions can be very different, a similar nonlinear growth behavior of graphene has been observed for different metal substrates. To und…
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…
Chemical Vapor Deposition Growth of Graphene using Other Hydrocarbon Sources
Zhancheng Li, Ping Wu, Chenxi Wang +7
Graphene has attracted a lot of research interests due to its exotic properties and a wide spectrum of potential applications. Chemical vapor deposition (CVD) from gaseous hydrocar…
First-Principles Thermodynamics of Graphene Growth on Cu Surface
Wenhua Zhang, Ping Wu, Zhenyu Li +1
Chemical vapor deposition (CVD) is an important method to synthesis grapheme on a substract. Recently, Cu becomes the most popular CVD substrate for graphene growth. Here, we combi…
Coalescence of Carbon Atoms on Cu (111) Surface: Emergence of a Stable Bridging-Metal Structure Motif
Ping Wu, Wenhua Zhang, Zhenyu Li +2
By combining first principles transition state location and molecular dynamics simulation, we unambiguously identify a carbon atom approaching induced bridging metal structure form…
