Electronic properties of grains and grain boundaries in graphene grown by chemical vapor deposition
We synthesize hexagonal shaped single-crystal graphene, with edges parallel to the zig-zag orientations, by ambient pressure CVD on polycrystalline Cu foils. We measure the electronic properties of such grains as well as of individual graphene grain boundaries, formed when two grains merged during the growth. The grain boundaries are visualized using Raman mapping of the D band intensity, and w...
متن کاملGrowth and properties of few-layer graphene prepared by chemical vapor deposition
The structure and the electrical, mechanical and optical properties of few-layer graphene (FLG) synthesized by chemical vapor deposition (CVD) on a Ni-coated substrate were studied. Atomic resolution transmission electron microscope (TEM) images show highly crystalline single-layer parts of the sample changing to multi-layer domains where crystal boundaries are connected by chemical bonds. This...

متن کاملGrain boundaries in graphene grown by chemical vapor deposition
The scientific literature on grain boundaries (GBs) in graphene was reviewed. The review focuses mainly on the experimental findings on graphene grown by chemical vapor deposition (CVD) under a very wide range of experimental conditions (temperature, pressure hydrogen/hydrocarbon ratio, gas flow velocity and substrates). Differences were found in the GBs depending on the origin of graphene: in ...
متن کاملSingle- and few-layer graphene growth on stainless steel substrates by direct thermal chemical vapor deposition.
Increasing interest in graphene research in basic sciences and applications emphasizes the need for an economical means of synthesizing it. We report a method for the synthesis of graphene on commercially available stainless steel foils using direct thermal chemical vapor deposition. Our method of synthesis and the use of relatively cheap precursors such as ethanol (CH(3)CH(2)OH) as a source of...
