Grapheneis an allotrope of carbon in the form of a two-dimensional, atomic-scale, honey-comb lattice in which one atom forms each vertex. It is the basic structural element of other allotropes, including graphite, charcoal, carbon nanotubes and fullerenes. It can also be considered as an indefinitely large aromatic molecule, the ultimate case of the family of flat polycyclic aromatic hydrocarbons. Scientists have theorized about graphene for decades. The material was later rediscovered, isolated and characterized in 2004 by Andre Geim and Konstantin Novoselov at the University of Manchester.Research was informed by existing theoretical descriptions of its composition, structure and properties. This work resulted in the two winning the Nobel Prize in Physics in 2010 "for groundbreaking experiments regarding the two-dimensional material graphene."
Graphene is currently the world's thinnest but also one of the most hard nano materials, it is almost completely transparent, absorbed only 2.3% of the light; thermal conductivity up to 5300 w / M - K, because of its low resistivity, electrons move fast and therefore are expected to be used to develop more thin, conductive speed faster, a new generation of electronic components or transistor.
