Event Information:
A peculiar electronic state in graphene nanoribbons (GNRs) which is localized only at the zigzag
type edge, the so called “edge stateâ€, was proposed in 1996 by M. Fujita and his coworkers [1]. In
2005−2006, the existence of the edge state was verified by scanning tunneling microscopy and
spectroscopy (STM/S) measurements at zigzag step edges on graphite surfaces by two groups
including ourselves [2,3]. In very narrow GNRs of widths less than ∼20 nm with zigzag edges on
both sides (zGNRs), the edge atoms are predicted to possess high spin polarizations (10−20%) even
