Substrate patterning creates p-n junctions in graphene Date: December 10, 2012 Source: Georgia Institute of Technology, Research Communications Summary: ...

They then dipped a thin film of graphene oxide into the solution and allowed it to dry. The Xenon lamp delivered a brief, intense flash of light, which was absorbed by the graphene oxide, heating ...

To construct the catalyst system, photogenerated electrons in titanium dioxide nanoparticles are first transferred into the graphene oxide substrate. Some of these electrons are used to improve ...

Graphene substrate improves the conductivity of carbon nanotube network ... which are expected to replace the metal-oxide films that are currently used.

Graphene–a flat single layer of carbon atoms–can transport electrons at remarkable speeds, making it a promising material for electronic devices. Until recently, researchers had been able to ...

However, it is difficult to scale, due to the need to deposit large quantities of GO on substrates. Reduced Graphene Oxide. As mentioned above, GO is reduced to obtain rGO (Figure 1). This process is ...

The solution-processability of graphene derivatives allows the fabrication of inorganic-graphene or organic-graphene composites 10 to be achieved readily using wet chemistry methods. Graphene hybrid ...

Before the paper saw light, it had been considered that such a phenomenon could only observed at 917 C temperatures or above. Gamma-iron nanoparticles were grown on a graphene oxide substrate. Our ...

Graphene is the thinnest imaginable material; it is just one atomic layer of carbon atoms. Rolling this into a cylinder makes a carbon nanotube, which is better suited to carrying electricity in ...
