Abstract  

Graphene nanoribbons (GNRs) are quasi one-dimensional narrow strips of graphene comprised of sp²-hybridized carbon atoms arranged into hexagonal honeycomb lattice configurations. GNRs possess high mobility and current-carrying capability, sizeable bandgap and versatile electronic properties, which make them promising candidates for quantum electronic applications. The high aspect ratio, abundant edges, conductivity, and propensity for functionalization make GNRs an attractive material that draws interest from a wide range of fields, including chemistry, physics, materials science, and biology. GNRs have already found use in various applications such as sensors, conductive films, polymer composites, batteries, energy-conversion/storage devices, bioimaging, DNA sequencing, and neurophysiological recovery. With the advancements in the preparation technology of GNRs, GNRs with different structures have been prepared and studied. Results reveal that GNRs have good photoelectric characteristics, providing them broad application prospects in quantum computing and dissipative microelectronic devices.
