Write Circuits on Graphene: A heated AFM tip can draw nanometers-wide conductive lines on graphene oxide

Tuesday, June 15, 2010

Researchers at the Georgia Institute of Technology and the U.S. Naval Research Laboratory "write" nanoribbons on a surface rather than cutting graphene.

Hot wire: An AFM tip heated to over 150 °C can etch an insulating graphene oxide surface to create thin conductive nanoscale wires.
