Suspended monolayer graphene on TEM grid substrate (Quantifoil gold)

半岛bd体育手机客户端 说明

一般描述

Graphene is a unique one-atom thick, two dimensional allotrope of carbon. Several methods have been developed to synthesize graphene, such as; mechanical and chemical exfoliation, chemical vapor deposition, graphitization of silicon carbide, reduction of graphene oxides. Preparation of monolayer graphene on polyethylene terephthalate (PET) film has been reported in a study. The single layer of graphene can be transferred by clean transfer method.

应用

Graphene film on TEM grid is useful for high resolution TEM imaging of nanoscale materials because it preserves the same focal plane over the whole grid mesh.
