Spring 'blockbuster' movie now showing
Date:3/31/2009

work which appears in the March 27, 2009 issue of the journal Science. The paper is entitled, "Graphene at the Edge: Stability and Dynamics." Co-authoring this paper with Zettl were ağlar Girit, Jannik Meyer, Rolf Erni, Marta Rossell, Christian Kisielowski, Li Yang, Cheol-Hwan Park, Michael Crommie, Marvin Cohen and Steven Louie.

In their paper, the authors credit the unique capabilities of TEAM 0.5 for making their movie possible. TEAM stands for Transmission Electron Aberration-corrected Microscope. The newest instrument at Berkeley Lab's National Center for Electron Microscopy (NCEM) - a DOE national user facility and the country's premier center for electron microscopy and microcharacterization - TEAM 0.5 is capable of producing images with half angstrom resolution, which is less than the diameter of a single hydrogen atom.

Said NCEM director Ulrich Dahmen of this achievement with TEAM 0.5, "The real-time observation of the movements of edge atoms could lead to a new level of understanding and control of nanomaterials. With further advances in electron-optical correctors and detectors it may become possible to increase the sensitivity and speed of such observations, and begin to see a live view of many other reactions at the atomic scale."

Rubbing graphene off the end of a pencil tip and suspending the specimen in an observation grid, Zettl and his colleagues used prolonged irradiation from TEAM 0.5's electron beam (set at 80 kV) to introduce a hole into the graphene's pristine hexagonal carbon lattice. Focusing the beam to a spot on the sheet blows out the exposed carbon atoms to create the hole. Since atoms at the edge of the hole are continually being ejected from the lattice by electrons from the beam the size of the hole grows. The researchers used the same TEAM 0.5 electron beam to record for analysis a movie showing the growth of the hole and the rearrangement of the carbon atoms.
