Advance in Close‐Edged Graphene Nanoribbon: Property Investigation and Structure Fabrication. Issue 29 (20th January 2019) - He, Maoshuai
Abstract: The absence of dangling bonds in close‐edged graphene nanoribbons (CEGNRs) confers upon them a series of fascinating properties, especially when compared with cylindrical carbon nanotubes and open‐edged GNRs. Here, the configuration of CEGNRs is described, followed by the structure‐related properties, including mechanical, thermal, electrical, optical, and magnetic properties. Based on the unique structures and extraordinary properties, their potential applications in a variety of fields, such as field‐effect transistors, energy suppliers, nanoactuators, and fibers, are discussed. Remarkably, the strategies applied for generating CEGNRs, mainly from the collapse of carbon nanotubes and graphene tubes, are depicted in detail. Finally, the prospects in the research area of CEGNRs are proposed. Abstract : Close‐edged graphene nanoribbons exhibit extraordinary properties and are attractive for many potential applications. The precondition to realize their applications is to synthesize them under controlled conditions. A number of strategies applied for generating close‐edged graphene nanoribbons are presented. Particularly, the collapse of carbon nanotubes, which is a facile means for close‐edged graphene nanoribbon generation, is well addressed.
