Graphene

2-dimensional, crystalline allotrope of carbon

 

 

Allotrope : property of chemical elements to exist in two or more forms.

Graphene is fundamentally one single layer of graphite, a layer of carbon atoms arranged in a honeycomb (hexagonal) lattice.

Graphene has many uncommon properties. It is the strongest material ever tested, efficiently conducts heat and electricity, and is nearly transparent. Graphene shows a large and nonlinear diamagnetism, greater than that of graphite, and can be levitated by neodymium magnets.
