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 ...

Lower Limits of Contact Resistance in Phosphorene Nanodevices with Edge Contacts
Nanomaterials, 2022 Edge contacts are promising for improving carrier injection and contact resistance in devices based on two-dimensional (2D) materials, among which monolayer black phosphorus (BP), or phosphorene, is especially attractive for device applications.

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 ...

Graphene nanoribbons with zigzag and armchair edges prepared by scanning tunneling microscope lithography on gold substrates [PDF]
, 2014 The properties of graphene nanoribbons are dependent on both the nanoribbon width and the crystallographic orientation of the edges. Scanning tunneling microscope lithography is a method which is able to create graphene nanoribbons with well defined edge

Functionalization of Graphene Nanoribbons [PDF]
, 2012 With the synthesis of a single atomic plane of graphite, namely, graphene honeycomb structure, a new perspective for carbon-based electronics is opened. The one-dimensional graphene nanoribbons (GNRs) have different band-gap values depending on their edge shape and width.

Charge transport in topological graphene nanoribbons and nanoribbon heterostructures [PDF]
Physical Review B, 2022 Although it is generally accepted that structural parameters like width, shape, and edge structure crucially affect the electronic characteristics of graphene nanoribbons (GNRs), the exact relationship between geometry and charge transport remains largely unexplored.

In situ transmission electron microscopy of individual carbon nanotetrahedron/nanoribbon structures in Joule heating [PDF]
, 2014 Collapse of a carbon nanotube results in the formation of a nanoribbon, and a switching of the collapse direction yields a nanotetrahedron in the middle of a nanoribbon.

Electronic transmission in Graphene suppressed by interlayer interference
AIP Advances, 2013 We investigate electronic transport property of a graphene monolayer covered by a graphene nanoribbon. We demonstrate that electronic transmission of a monolayer can be reduced when covered by a nanoribbon.

Nanoribbon Biosensor-Based Detection of microRNA Markers of Prostate Cancer
Sensors, 2023 Prostate cancer (PC) is one of the major causes of death among elderly men. PC is often diagnosed later in progression due to asymptomatic early stages. Early detection of PC is thus crucial for effective PC treatment.
