Importantly, the graphene/silicon carbide interface is only partially stable and is readily passivated by nearly any element, if the element has access to this interface. The team provides this access by poking holes in the graphene with an oxygen plasma, and then they evaporate pure metal powders onto the surface at high temperatures.

Graphene on silicon carbide can store energy

Graphene on silicon carbide can store energy “Graphene on silicon carbide can be made in larger areas than other types of graphene. If we can change the properties of the material in a controlled manner, it may be possible to tailor the surface for other functions.

New Graphene Fabriion Method Uses Silicon Carbide …

In creating their graphene nanostructures, De Heer and his research team first use conventional microelectronics techniques to etch tiny "steps" – or contours – into a silicon carbide wafer. They then heat the contoured wafer to approximately 1,500 degrees Celsius, which initiates melting that polishes any rough edges left by the etching process.

Graphene On Silicon Carbide Can Store Energy

When silicon carbide is heated to 2000 C, silicon atoms on the surface moves to the vapor phase and only the carbon atoms remain. The graphene does not react easily with its surroundings due to the high quality of the graphene layer and its innate inertness, while appliions often rely on controlled interaction between the material and the surroundings, like gas molecules.
