What is armchair graphene?

Armchair nanoribbons are metallic or semiconducting and present spin polarized edges. Their gap opens thanks to an unusual antiferromagnetic coupling between the magnetic moments at opposite edge carbon atoms.

What are graphene nanoribbons used for?

3 Graphene Nanoribbons. GNRs have been predicted to display high electrical and thermal conductivity, high breakdown current density, and low noise, which suggest that they can be used as an alternative to copper for integrated circuit interconnects.

What is Nanoribbon meaning?

A nanostructure in the form of a ribbon. noun.

What is an armchair structure?

The structure defines the logic of the product, where the metal core is sometimes evident, others partly concealed, thereby giving the sofa or armchair an absolutely informal appearance.

What is carbon Nanoribbon?

Introduction. Graphene is a one-atomic-layer thick two-dimensional material made of carbon atoms arranged in a honeycomb structure. Graphene nanoribbons (GNRs) are narrow strips of graphene.

What is zigzag CNT?

Definition. A single walled carbon nanotube with (n,m) indices equal to (n,0) or (0,m). Zigzag carbon nanotubes have a chiral angle of 0° and can be either metallic or semiconducting.

What is Swcnt?

Single-walled carbon nanotubes (SWCNTs) are cylindrical graphitic tubules with diameters of approximately 1.0 nm, and they have a variety of electronic properties that depend on how the graphene sheet is rolled, which is referred to as chirality [1].

What’s the difference between graphene and graphene oxide?

Graphene is a material made of carbon atoms that are bonded together in a repeating pattern of hexagons. Graphene oxide is an oxidized form of graphene, laced with oxygen-containing groups. It is considered easy to process since it is dispersible in water (and other solvents), and it can even be used to make graphene.
