Local Peeling of Graphene

摘要

"Perfection is finally attained not when there is no longer anything to add, but when there is no longer anything to take away," noted Antoine de Saint-Exupery (1). He could have been writing about graphene sheets, just an atomic layer or two thick, which have properties much more interesting than those of the bulk. From the time when graphite would be rubbed on an insulating surface with the hope that one of the exfoliated flakes would be a single layer, graphene manufacture has progressed rapidly and is now routinely grown on or transferred onto many substrates, even up to sizes large enough for TV displays (2).
