Our work on the surface potential of few-layer graphene films is featured as the recent cover article of the January 2009 issue of Nano Letters.
Using electrostatic force microscopy we probe the charge screening features of few-layer graphene films.
The work was performed in collaboration with S. S. Datta, E. J. Mele , and A. T. Johnson.
Crystallographic etching of few-layer graphene which we recently reported in Nano Letters was highlighted by Nature Nanotechnology.
By utilizing metallic nanoparticles, we are able to etch few-layer graphene samples along specific crystallographic directions.
This work was performed in collaboration with S. S. Datta, S. M. Khamis , and A. T. Johnson.
