Tracking topological conditions in graphene

Scientists have been able to demonstrate that graphene nanostructures can be generated by annealing of a nanostructured silicon carbide crystal for a few years. "These two-dimensional, spatially strongly restricted carbon ...

Team develops method for trapping elusive electrons

Graphene's unique 2-D structure means that electrons travel through it differently than in most other materials. One consequence of this unique transport is that applying a voltage doesn't stop the electrons like it does ...

Electron correlations in carbon nanostructures

New materials are needed to further reduce the size of electronic components and thus make devices such as laptops and smartphones faster and more efficient. Tiny nanostructures of the novel material graphene are promising ...

How do atoms vibrate in graphene nanostructures?

In order to understand advanced materials like graphene nanostructures and optimize them for devices in nano-, opto- and quantum-technology it is crucial to understand how phonons—the vibration of atoms in solids—influence ...

From foe to friend: Graphene catalyzes the C-C bond formation

Graphene monolayers can be epitaxially grown on many single-crystal metal surfaces under ultra-high vacuum. On one side, these monolayers protect highly reactive metallic surfaces from contaminants, but on the other side, ...

Detecting light in a different dimension

Scientists from the Center for Functional Nanomaterials (CFN)—a U.S. Department of Energy (DOE) Office of Science User Facility at Brookhaven National Laboratory—have dramatically improved the response of graphene to ...

How infrared light can be captured by graphene nanostructures

Researchers from CIC nanoGUNE, in collaboration with ICFO and Graphenea, have demonstrated how infrared light can be captured by nanostructures made of graphene. This happens when light couples to charge oscillations in the ...
