Event Information:

A peculiar electronic state in graphene nanoribbons (GNRs) which is localized only at the zigzag
type edge, the so called “edge state”, 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
