Graphene Nanoribbons

                Graphene nanoribbons(GNRs) are narrow strips of graphene.  These are also called as nano-graphe ribbons or nano-graphite ribbons. It has width less than 100nm.GRNs are planer, finite, quasi-one-dimensional graphene structures.

Discovered by:

                    Examining  the nanoscale size &  edge effects  of graphene GRNs were discovered by Mitsutaka Fujita(Japanese physicist).

Process of making Graphene nanoribbons:

Synthesis Methods:

                      3 steps for fabrication of GNRs

1. cutting from graphene using lithography
2. bottom-up synthesis from polycyclic molecules
3. unzipping of carbon nanotubes(CNTs).
