Metallic Graphene Nanoribbons [PDF]

Nano-Micro Letters, 2021
AbstractIsolated graphene nanoribbons (GNRs) usually have energy gaps, which scale with their widths, owing to the lateral quantum confinement effect of GNRs. The absence of metallic GNRs limits their applications in device interconnects or being one-dimensional physics platform to research amazing properties based on metallicity.

Molecular nanoribbon gels

Chemical Science, 2022
Herein, we show that twisted molecular nanoribbons with as many as 322 atoms in the aromatic core are efficient gelators capable of self-assembling into ordered π-gels with morphologies and sol–gel transitions that vary with the length of the nanoribbon.

Ultranarrow TaS₂ Nanoribbons [PDF]

Nano Letters, 2021
Imposing additional confinement in two-dimensional (2D) materials can yield further control over the associated electronic, optical, and topological properties. However, synthesis of ultra-narrow nanoribbons (NRs) remains a challenge, particularly for the transition metal dichalcogenides (TMDs), and synthesizing TMD NRs narrower than 50 nm has remained

Anthracene‐Porphyrin Nanoribbons

Angewandte Chemie International Edition, 2023
Abstract π‐Conjugated nanoribbons attract interest because of their unusual electronic structures and charge‐transport behavior. Here, we report the synthesis of a series of fully edge‐fused porphyrin‐anthracene oligomeric ribbons (dimer and trimer), together with a computational study of the corresponding ...

Modeling nanoribbon peeling [PDF]

Nanoscale, 2019
Lifting and peeling of 2D materials and nanoribbons off surfaces is common in nanoscience. Solution of an analytical model shows that structural lubricity makes the peeling of a nanoribbon or film radically different from the standard description of peeling of immobile, fully glued films.

Graphene nanoribbon heterojunctions [PDF]

Nature Nanotechnology, 2014
Despite graphene's remarkable electronic properties, the lack of an electronic bandgap severely limits its potential for applications in digital electronics. In contrast to extended films, narrow strips of graphene (called graphene nanoribbons) are semiconductors through quantum confinement, with a bandgap that can be tuned as a function of the ...

Production of phosphorene nanoribbons [PDF]

Nature, 2019
Phosphorene is a mono-elemental, two-dimensional (2D) substance with outstanding, highly directional properties and a bandgap that depends on the number of layers of the material1-8. Nanoribbons, meanwhile, combine the flexibility and unidirectional properties of one-dimensional nanomaterials, the high surface area of 2D nanomaterials and the electron ...

Nanoribbon-Based Electronic Detection of a Glioma-Associated Circular miRNA

Biosensors, 2021
Nanoribbon chips, based on “silicon-on-insulator” structures (SOI-NR chips), have been fabricated. These SOI-NR chips, whose surface was sensitized with covalently immobilized oligonucleotide molecular probes (oDNA probes), have been employed for the ...

Phase coherent transport in graphene nanoribbons and graphene nanoribbon arrays [PDF]

Physical Review B, 2012
We have experimentally investigated quantum interference corrections to the conductivity of graphene nanoribbons at temperatures down to 20 mK studying both weak localization (WL) and universal conductance fluctuations (UCF). Since in individual nanoribbons at millikelvin temperatures the UCFs strongly mask the weak localization feature we employ both ...
