Large-scale production of Graphene Nanoribbons with controlled width: Electrical Properties of Graphene Nanoribbon Films*

In this talk, we will demonstrate a novel large scale production (10$^{7}$ ribbons/ sec) scheme for several microns long, smooth-edged graphene nanoribbons (GNRs) with controlled widths (from 5 -- 50 nm). We will then present detailed structural, optical and electrical properties of GNR-films $\sim $ 100 nm thick produced from 5, 15, and 45 nm wide GNRs; including their band-gap evolution and electrical transport mechanism. The high throughput method to synthesize GNR of high-quality will be a quantum leap in the graphene research. The work indents to bridge the gaps in the understanding of monodisperse-GNR film properties.
