Half-metallic graphene nanoribbons [PDF]

open access: yesNature, 2006
Electrical current can be completely spin polarized in a class of materials known as half-metals, as a result of the coexistence of metallic nature for electrons with one spin orientation and insulating for electrons with the other. Such asymmetric electronic states for the different spins have been predicted for some ferromagnetic metals - for example,

Enhancing The Extremely High Thermal Conduction of Graphene Nanoribbons

open access: yesFrontiers in Physics, 2013
Graphene and Graphene nanoribbons (GNRs) are found to have superior high thermal conductivity favorable for high-performance heat dissipation. In this letter, by using molecular dynamics simulations, we show that constructing specific structure can ...

Electronic structures of SiC nanoribbons [PDF]

open access: yesThe Journal of Chemical Physics, 2008
Electronic structures of SiC nanoribbons have been studied by spin-polarized first-principles calculations. The armchair nanoribbons are nonmagnetic semiconductors, while the zigzag nanoribbons are magnetic metals. The spin polarization in the zigzag SiC nanoribbons is originated from the unpaired electrons localized on the ribbon edges. Interestingly,

A Helicene Nanoribbon with Greatly Amplified Chirality

open access: yes, 2018
We report the synthesis and characterization of a chiral, shape-persistent, perylene-diimide-based nanoribbon. Specifically, the fusion of three perylene-diimide monomers with intervening naphthalene subunits resulted in a helical superstructure with two

High-Yield Growth and Tunable Morphology of Bi2Se3 Nanoribbons Synthesized on Thermally Dewetted Au

open access: yesNanomaterials, 2021
The yield and morphology (length, width, thickness) of stoichiometric Bi2Se3 nanoribbons grown by physical vapor deposition is studied as a function of the diameters and areal number density of the Au catalyst nanoparticles of mean diameters 8–150 nm ...

Nanoribbon Biosensor in the Detection of miRNAs Associated with Colorectal Cancer

open access: yesMicromachines, 2021
A nanoribbon biosensor (NRBS) was developed to register synthetic DNAs that simulate and are analogous to miRNA-17-3p associated with colorectal cancer.

Porphyrin-fused graphene nanoribbons

open access: yesNature Chemistry, 2023
Abstract Graphene nanoribbons (GNRs), nanometre-wide strips of graphene, are promising materials for fabricating electronic devices. Many GNRs have been reported, yet no scalable strategies are known for synthesizing GNRs with metal atoms and heteroaromatic units at precisely defined positions in the conjugated ...

Phthalocyanine Nanoribbons Fabricated by Template-Free Electrophoretic Deposition

open access: yesInternational Journal of Electrochemical Science, 2013
A simple method of constructing organic phthalocyanine nanoribbons by template-free electrophoretic deposition is provided. Copper phthalocyanine molecules in low protonation degree driven under electric field enable the intermolecular ordered assembling

Thermoelectric Conversion From Interface Thermophoresis and Piezoelectric Effects

open access: yesFrontiers in Physics, 2022
Piezoelectric effect has proved itself to be a promising energy conversion mechanism that can convert mechanical energy into electricity. Here, we propose an indirect thermoelectric conversion mechanism based on a combination of the thermophoresis and ...
