Perfect conductorChern-Simons theorymagnetic flux expulsionSUPERCONDUCTIVITYTEMPERATURETERMHere, we show that the graphene sheet, which is designed to behave a band insulator, can be turned into a perfect conductor, when the difference of the current from the two valleys gets coupled to an Abelian ...

But we need a reliable way to mass produce graphene in large sheets so they can be sold to companies that manufacture transistors, for example. And several groups are investigating ways to do this, to make large quantities of graphene cost effectively. As you know, a semi-conductor is a ma...
presumably depending on how the large sheets happen to pack. The mmA/macrocycle value expected at perfect monolayer packing both from GIXD and DFT is 71 Å2. It is thus highly unlikely that1could be present as a bilayer, for which
The classification of graphene as metal, non-metal or semimetal is still a matter of debate and requires further research [3]. But, due to the presence of metallic layers with very low bandgaps, it can be treated as a semimetal with an exceptional theoretical background [2,3]. As a ...
CVD graphene is grown directly on the conductor, and the strong binding between the two prevents them separating from each other36, 37. These give the electrodes strong stability and long life. The CVD graphene-based sensor has been used to detect levodopa38 and glucose39, 40. Further ...
Alternatively, GO can be used as a solid-state electron mediator for water splitting in the Z-scheme photocatalysis system [22] to overcome the problems with electron recombination and transportability. Iwase’s group [35] constructed a model system of using GO as solid electron mediator, BiVO4...
Self-consistent field theory is used to obtain the non-local plasmon dispersion relation of monolayer graphene which is Coulomb-coupled to a thick conductor. We calculate numerically the undamped plasmon excitation spectrum for arbitrary wave number. For gapped graphene, both the low-frequency (...
This causes a phasedifference and, therefore, an interference between partial waves encircling the conductor inopposite directions. The ordered phases stabilize each other up into the millikelvin range. The discoveries of the carbon nanostructures, such as the 0D fullerenes [5.1] and their mass ...
Graphene, a form of carbon that comes in sheets a single atom thick, has gained a reputation as a wonder material. It is the best conductor yet discovered of heat at room temperature and is 40 times stronger than steel. It is also a semiconductor whose electrical conductivity is 1,000 tim...
