As I posted earlier, the Nobel Prize in Physics 2010 was awarded jointly to Andre Geim and Konstantin Novoselov “for groundbreaking experiments regarding the two-dimensional material graphene”
It seems there is no controversy that “the first graphene samples formed were produced by pulling atom thick layers from a sample of graphite using sticky tape”.
But whether the graphite sample was actually lead flakes from a pencil and whether the sticky tape was actually Scotch tape is more uncertain. Nevertheless, it is now the stuff of urban legend and the subject of cartoons.
sticky tape + pencil = graphene
