Description: The movie shows a high-resolution transmission electron microscopy study of the structure and dynamics of graphene at the edge of a hole in a suspended, single atomic layer of graphene. The injection of electrons causes ejection of carbon atoms, leading to rearrangement of the bonds at the edges into a zigzag configuration, which represents the most stable form. This study of an ideal low-dimensional interface, a hole in graphene, exhibits the complex behavior of atoms at a boundary. Credit: University of California, Berkeley.
