Electronic life on the edge

As far back as the 1990s, long before anyone had actually isolated graphene � a honeycomb lattice of carbon just one atom thick � theorists were predicting extraordinary properties at the edges of graphene nanoribbons. Now physicists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), and their colleagues at the University of California at Berkeley, Stanford University, and other institutions, have made the first precise measurements of the "edge states" of well-ordered nanoribbons........
