Bay, fjord, cove, armchair and zigzag—chemists use terms such as these to describe the shapes taken by the edges of nanographene. Graphene consists of a single-layered carbon structure in which each carbon atom is surrounded by three others. This creates a pattern reminiscent of a honeycomb, with atoms in each of the corners. Nanographene is a promising candidate to bring microelectronics down to the nano-scale and a likely substitute for silicon.
