Graphene (/ ˈɡræfiːn /) [1] is a carbon allotrope consisting of a single layer of atoms arranged in a honeycomb planar nanostructure. [2][3] The name "graphene" is derived from " graphite " and the suffix -ene, indicating the presence of double bonds within the carbon structure.

graphene, a two-dimensional form of crystalline carbon, either a single layer of carbon atoms forming a honeycomb (hexagonal) lattice or several coupled layers of this honeycomb structure. The word graphene, when used without specifying the form (e.g., bilayer graphene, multilayer graphene), usually refers to single-layer graphene.

Graphene is a single layer of carbon atoms arranged in a hexagonal lattice structure, forming a two-dimensional (2D) material with exceptional mechanical, electrical, and thermal properties. It is widely studied for its potential use in various fields such …

Graphene stands out for being tough, flexible, light, and with a high resistance. It's calculated that this material is 200 times more resistant than steel and five times lighter than aluminum. With these properties, graphene has applications in the energy, construction, health, and …

2022年10月14日 · We have evaluated some of the most recent breakthroughs in the synthesis and applications of graphene and graphene-based nanomaterials. This review includes three major categories. The first section consists of an overview of the structure and properties, including thermal, optical, and electrical transport.

Graphene - Properties, Structure, Uses: There is another reason why graphene is of special interest to fundamental science: it is the first and simplest example of a two-dimensional crystal—that is, a solid material that contains just a single layer of …

2022年3月8日 · Electronic properties. Graphene has extremely high electrical current density (a million times that of copper) and intrinsic mobility (100 times that of silicon). Graphene has a lower resistivity than any other known material at room temperature, including silver.

Graphene is a single-atom thick layer of graphite with strong covalent bonds between each carbon atom. The atoms are arranged in hexagons. Its properties include: high melting and boiling...

2018年1月1日 · Graphene possesses many outstanding properties in terms of optical transparency, electric conductivity, mechanical strength, and thermal conductivity. Detailed properties will be discussed in Chapter 5 , Graphene Electronic Devices, while this chapter will simply cover the main ideas.

Here, we introduce the most important electronic and thermal properties of graphene, including its high conductivity, quantum Hall effect, Dirac fermions, high Seebeck coefficient and thermoelectric effects. We also present up-to-date graphene-based applications: optical devices, electronic and thermal sensors, and energy management systems.
