Soft lithography of graphene sheets via surface energy modification

초록

A simple and efficient soft lithographic process for an easily applicable patterning method for large-scale graphene sheets was demonstrated. The surface of an elastomeric stamp was functionalized with polar molecules to enhance the interfacial adhesive force between the stamp and the graphene layer. A specific graphene area was then patterned on the initial substrate and transferred to the target surface by contacting with the stamp.
