WebSingle-layer graphene was first unambiguously produced and identified in 2004, by the group of Andre Geim and Konstantin Novoselov, though they credit Hanns-Peter Boehm and his co-workers for the experimental discovery of graphene in 1962; while it had been explored theoretically by P. R. Wallace in 1947. Web3 dec. 2024 · Graphene is a new material that was first isolated in 2004 at the University of Manchester. It is made up of a single atom layer of graphite - the same graphite used in pencil lead. Geim and Novoselov first isolated graphene by repeatedly separating graphite fragments with sticky tape until they created one-atom-thick flakes.
