Graphene was discovered in 2004 by Andre Geim and Konstain Noselov, who won the Nobel Prize in 2010. It has a hexagonal structure formed by carbon atoms linked in planar sheets. Its main properties include being two-dimensional, transparent, highly conductive of heat and electricity, elastic, resistant, light, and flexible. Graphene could enable future technologies like screens, processors, memristors, and other electronic materials.
