Strachan Group

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.



Highlights
Group Members Receive Poster Presentation Awards

Two group members recently received poster presentation awards. Over the summer of 2009 graduate research assistant Abhishek Sundararajan was awarded first prize in the annual Department of Physics and Astronomy Poster Presentation Event. In the Fall of 2009 Jimmy Rop, a 2009 summer research assistant attending Berea College, was awarded 2nd prize at the annual meeting of the Kentucky Academy of Science.
