Graphene nanoribbons: Current status and challenges as quasi-one-dimensional nanomaterials

Abstract

The electronic structure of quasi-one-dimensional graphene nanoribbons (GNRs) is closely related to their width, boundary configuration and heteroatomic doping because of the quantum confinement effect and edge effect. Therefore, GNRs present novel electrical, magnetic and optical characteristics. 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. Herein, we review the research achievements of GNRs in recent years, focus on the advantages and disadvantages of the preparation methods of GNRs and provide some experimental basis for their application.
