Researchers at Rice University and Montreal Polytechnic analyzed the electromagnetic effects of junctions between nanotubes and graphene sheets. From top to bottom are a graphene/carbon nanotube ...

Moreover, this impressive mobility is little affected by changes in temperature or by the presence of excess charge on the graphene sheet. There also seems to be ample room for optimizing the ...

For example, could chemical tuning be used to alter the physical properties of graphene sheets? Indeed, could nanoelectronic devices be made from chemically functionalized graphene? Rather than ...

Forced to run a labyrinth of carbon atoms uniquely arranged in twisted stacks, electrons do some rather peculiar things.

Scientists in Brazil have made the largest chemically synthesised graphene sheet ever reported. Graphene – single-atom-thick sheets of carbon – is a material that has seemed full of possibilities ...

“Although a wide range of [superconductor] correlated phenomena have indeed been observed in the moiré TMDs, robust demonstration of superconductivity has remained absent,” the researchers said in a ...

The background is a colored scanning electron microscopy image of the graphene drumheads fabricated from a single layer of graphene exfoliated over an array of one micron-size pits etched in ...

In principle, graphene is the ideal material for these electrodes. Consisting of 2D sheets of carbon atoms, it has now been extensively studied since its initial characterization in the early 2000s.

The surface of graphene, a one atom thick sheet of carbon, can be randomly decorated with oxygen to create graphene oxide; a form of graphene that could have a significant impact on the chemical, ...
