US Patent 8057863 - Electrostatic force assisted deposition of graphene

http://www.freepatentsonline.com/8057863.html

This patent from the Regents of the University of California teaches a maskless deposition method for patterning graphene films to create ultrahigh mobility electronic devices. Claim 1 reads:

1. A method of depositing graphene comprising:

bringing a stamp into contact with a substrate over a contact area, the stamp having one or more layers of the graphene covering the contact area;

developing an electric field over the contact area; and

removing the stamp from the vicinity of the substrate which leaves at least a layer of the graphene substantially covering the contact area.
