What is graphene?
Quick Answer
Graphene is a single layer of carbon atoms arranged in a honeycomb pattern — one atom thick, incredibly strong and an excellent conductor.
The Full Story
Graphene is a two-dimensional form of carbon in which atoms bond in a flat hexagonal lattice. It was first isolated in 2004 by Andre Geim and Konstantin Novoselov at the University of Manchester, who peeled thin flakes from graphite using sticky tape. The discovery earned them the 2010 Nobel Prize in Physics. Graphene is often described as about 200 times stronger than steel, yet it is extremely light and flexible. It conducts heat and electricity exceptionally well and is almost transparent, absorbing only about 2.3% of light.
