The number of graphene layers determines specific properties. Both single-layer and bi-layer graphenes are zero band gap semiconductors because of the association between conduction and the valance ...
(Nanowerk News) Scientists have developed a new strategy to significantly boost the sensitivity of graphene-based sensors that detect molecules using Raman spectroscopy. By modulating the graphene's ...
Due to its high electron mobilities at ambient temperature and peculiar electronic behaviors like the quantum hall effect, which imitates massless transportation and results in high superconductivity, ...
Since its discovery in 2004, graphene has become a highly prized material in electronics applications owing to its unusual electronic structure. 1 Although graphene is only composed of carbon atoms, ...
Vertical graphene microstructures break the thickness-performance tradeoff in thermoacoustic speakers, enabling flexible ...
In the photonic synthetic dimension, the coupling of internal degrees of freedom of photons, such as frequency, spatial mode, and orbital angular momentum, generates extra dimensions in addition to ...
In the BLG double quantum dot used in this work, electrons (the blue spheres) have both an intrinsic angular momentum (spin, given by the arrows through the spheres) and a pseudo- spin (valley, given ...
