Raman spectroscopy investigations of chemically derived zigzag edge graphene nanoribbons

Raman spectroscopy investigations of chemically derived zigzag edge graphene nanoribbons

We fabricated graphene nanoribbons (GNRs) chemically derived from expandable graphite. All GNRs exhibit atomically smooth edges that extended over their entire length. We investigated four of the fabricated GNRs using Raman spectroscopy. Two of the investigated GNRs show Raman spectra with a missing...
