Electron Transport in Disordered Graphene Nanoribbons
Electron Transport in Disordered Graphene Nanoribbons
We report an electron transport study of lithographically fabricated graphene nanoribbons (GNRs) of various widths and lengths. At the charge neutrality point, a length-independent transport gap forms whose size is inversely proportional to the GNR width. In this gap, electrons are localized, and charge transport exhibits a transition between thermally …
