Definition: graphene

(1) See also grapheme.

(2) A carbon layer one atom thick derived from the mineral graphite. Looking like chicken wire and considered a 2D material, graphene is naturally found as layers making up graphite. The graphene layers are separated by various exfoliation methods.

Extraordinary Properties
Graphene's mechanical, electrical, optical, thermal and chemical properties are outstanding, and it has been touted as a "miracle material." The 2D sheets can be layered together, fabricated into wires (nanoribbons), flakes, disk-shaped platelets or quantum dots for many applications. In addition, graphene can be added to metals, ceramics, plastics and rubber to make products stronger, lighter, more heat resistant or more flexible.

As the most conductive material on the planet, in time, graphene is expected to supplant silicon in electronics fabrication; however, hurdles must be overcome. For example, graphene has no bandgap; the most essential semiconductor attribute. See bandgap.

Graphene is expected to be a foundation nanotechnology component that revolutionizes industries and future products. See nanotube and nanotechnology.

A 2D Graphene Layer

Resembling chicken wire, graphene layers are separated from graphite.

Graphene - From Soup to Nuts

Ron Mertens' Graphene Handbook educates the reader from the ground up about graphene's properties, shapes, uses and potential. A must read for anyone who wants to truly learn about this amazing material.
