Graphene nanoribbons (GNRs, also called nano-graphene ribbons or nano-graphite ribbons) are strips of graphene with width less than 100 nm. Graphene ribbons were introduced as a theoretical model by Mitsutaka Fujita and coauthors to examine the edge and nanoscale size effect in graphene.

2024年2月20日 · Graphene nanoribbons (GNRs) are narrow strips of graphene with widths ranging from a few nanometers to a few tens of nanometers. GNRs possess most of the excellent properties of graphene, while also exhibiting unique physical characteristics not found in graphene, such as an adjustable band gap and spin-polarized edge states.

2025年1月8日 · Here we report a general approach for designing and fabricating such ferromagnetic GNRs in the form of Janus GNRs (JGNRs) with two distinct edge configurations.

2022年6月7日 · Graphene nanoribbons (GNRs), defined as nanometer-wide strips of graphene, have attracted increasing attention as promising candidates for next-generation semiconductors. Here, the authors demonstrate a bottom-up strategy toward novel low band gap GNRs (Eg = 1.70 eV) with a well-defined cove-type periphery both in soln. and on a solid substrate ...

2024年3月27日 · Here we report the transfer-free direct growth of high-quality graphene nanoribbons (GNRs) in hBN stacks. The as-grown embedded GNRs exhibit highly desirable features being ultralong (up to...

2021年9月28日 · Graphene nanoribbons (GNRs) are a family of one-dimensional (1D) materials with a graphitic lattice structure. GNRs possess high mobility and current-carrying capability, sizeable bandgap and...

2020年9月10日 · Graphene nanoribbons (GNRs) are narrow lengthened strips of single-layer graphene. Among the graphene family of nanomaterials, GNRs are remarkable materials due to their attractive physical, chemical, electrical, mechanical, thermal, and optical properties.

2023年6月1日 · 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.

2021年6月6日 · With a two-step on-surface synthesis process, graphene nanoribbons can be fabricated with atomic precision, allowing precise control over width and edge structure. Meanwhile, a decade of research has resulted in a plethora of graphene nanoribbons having various structural and electronic properties.

Graphene nanoribbons (GNRs) are narrow strips of graphene. The quasi one-dimensional nature of GNRs results in additional advantages over graphene sheets, the more widely known two-dimensional counterpart to GNRs. For example, the high aspect ratio of GNRs significantly lowers the percolation threshold in conductive films and polymer composites ...
