Researchers with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), working with TEAM 0.5, the world’s most powerful transmission electron microscope, have made a movie that shows in real-time carbon atoms repositioning themselves around the edge of a hole that was punched into a graphene sheet. Viewers can observe how chemical bonds break and form as the suddenly volatile atoms are driven to find a stable configuration. This is the first ever live recording of the dynamics of carbon atoms in graphene. ( Science Daily )
The video above is not a simulation, but actual atoms re-arranging themselves to a more stable state, in order to counter-act the instability of the hole in the graphene. Graphene is a one-atom-thick planar sheet of sp2-bonded carbon atoms that are densely packed in a honeycomb crystal lattice. This image below is a 3-dimensional, false-color rendering of the hole in the graphene. (click to enlarge)
This is the bad-ass that led the team. His name is Alex Zettl.
His previous accomplishments included the first fully functional radio from a single carbon nanotube, and a nanoscale mass sensor that can weigh individual atoms. ( Berkley Lab )
