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 ...
Graphene is a form of carbon. As a substance, it is entirely new – not only the thinnest ever but also the strongest. As a conductor of electricity, it performs as well as copper. As a conductor of heat, it outperforms useful conducting metals such as silver and copper. It is... ...
a conductor like copper, a semiconductor like silicon, and an insulator like rubber. but two-dimensional analogues exist for each of these. combine a graphene conductor, a boron nitride insulator, and a molybdenum disulfide semiconductor, and you could built a flexible circuit—one you could sew...
Graphene Oxide films can be deposited on essentially any substrate, and later converted into a conductor. This is why GO is especially fit for use in the production of transparent conductive films, like the ones used for flexible electronics, solar cells, chemical sensors and more. GO is even ...
From the viewpoint of its electronic properties,grapheneis a zero-gap semiconductor with unique electronic properties originating from the fact that charge carriers in graphene are described by a Dirac-like equation, rather than the usual Schrödinger equation[2]. As a consequence of its perfect ...
Graphene is known as the material of the future due to its excellent properties and multiple applications. Discover its full potential!
Development of printed conductive inks for electronic applications has grown rapidly due to widening applications in transistors1, sensors2, antennas3,4, radio frequency identification (RFID)5,6,7tags, wearable electronics8, etc. As conductor is the core component in printed electronics, efforts have...
Graphene has recently emerged as a sensational nanocarbon with unusual properties [1,2]. It is a gapless material with ballistic conduction at room temperature and high carrier mobility [3]. It possesses a high theoretical surface area of 2630 m2/g and thermal conductivity of ∼5000 W/mK [...
In fact, it behaves much more like a metal (though the way it conducts electricity is very different), and that's led some scientists to describe it as a semimetal or a semiconductor (a material mid-way between a conductor and an insulator, such as silicon and germanium). Even so, it...
As a conductive nanomaterial, graphene has huge potentials in nerve function restoration by promoting electrical signal transduction and metabolic activities with unique topological properties. Polydopamine (PDA) and arginylglycylaspartic acid (RGD) can improve cell adhesion in tissue engineering. Here we ...
