According to Konstantin Sergeyevich Novoselov (the 2010 Nobel Physics Prize winner), Samsung managed to make a 40-inch diagonal (102 cm) Graphene sheet. Back in June 2010 it was reported that Samsung made a 30-inch sheet, and Konstantin says he has a sample of this sheet and he's using it for experiments.
