Graphene nanoribbons (GNRs), narrow stripes of graphene with a width typically smaller than 100 nm, have recently attracted extensive interests because of their unique structure-dependent electronic properties and promising applications in nanoelectronics and spintronics. We produced graphene nanoribbonds of high-quality, selected number of layers and low cost by means of a chemical method based on the growth of colloidal suspensions. Furthemore, by means of this process we obtained graphene nanoribbons with a low content of oxidized forms. This method could offer a low-cost route to large-scale graphene production. The structures were characterized by many AFM and Raman spectroscopy. The investigation of vibrational properties of graphene nanoribbons is of great interest for the physical understanding of these structures

Abstract
Graphene nanoribbons (GNRs), narrow stripes of graphene with a width typically smaller than 100 nm, have recently attracted extensive interests because of their unique structure-dependent electronic properties and promising applications in nanoelectronics and spintronics. We produced graphene nanoribbonds of high-quality, selected number of layers and low cost by means of a chemical method based on the growth of colloidal suspensions. Furthemore, by means of this process we obtained graphene nanoribbons with a low content of oxidized forms. This method could offer a low-cost route to large-scale graphene production. The structures were characterized by many AFM and Raman spectroscopy. The investigation of vibrational properties of graphene nanoribbons is of great interest for the physical understanding of these structuresI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
