title: Laser-induced unzipping of carbon nanotubes to yield graphene nanoribbons.
abstract: Irradiation of undoped and doped multi-walled carbon nanotubes by an excimer laser (energy ∼200-350 mJ) yields graphene nanoribbons (GNRs). The GNRs so obtained have been characterized by transmission electron microscopy, atomic force microscopy and Raman spectroscopy.
