Graphene folding on flat substrates - AIP Publishing
2014年10月23日 · We present a combined experimental-theoretical study of graphene folding on flat substrates. The structure and deformation of the folded graphene sheet are experimentally characterized by atomic force microscopy. The local graphene folding behaviors are interpreted based on nonlinear continuum mechanics modeling and molecular dynamics simulations.
Single-crystal, large-area, fold-free monolayer graphene
2021年8月25日 · Here we explore the wrinkling/folding process for graphene films grown from an ethylene precursor on single-crystal Cu–Ni (111) foils. We identify a critical growth temperature (1,030 kelvin)...

2020年4月30日 · Even in the explosively growing areas of 2D materials, for example, the recent demonstration of graphene kirigami 4 and origami 5 has opened a new dimension of material engineering promising for...
Graphene Folding in Si Rich Carbon Nanofibers for Highly Stable, High ...
2016年2月8日 · Silicon nanoparticles (Si NPs) wrapped by graphene in carbon nanofibers were obtained via electrospinning and subsequent thermal treatment. In this study, water-soluble poly (vinyl alcohol) (PVA) with low carbon yield is selected to make the process water-based and to achieve a high silicon yield in the composite.
Nanomechanical z-shape folding of graphene on flat substrate
2016年12月1日 · Graphene folding is an essential process in the design and manufacturing of graphene origami. Here we report the nanomechanical z-shape (accordion) folding of single graphene sheets on flat substrates by using atomic force microscopy techniques.
Phys. Rev. B 83, 245433 (2011) - Multiply folded graphene
2011年6月27日 · For graphene, an ideal two-dimensional material, folding may transform it to complex shapes with new and distinct properties. Here, we present experimental results that folded structures in graphene, termed grafold, exist, and their formations can be controlled by introducing anisotropic surface curvature during graphene synthesis or transfer ...
