Definition of graphene in English:

graphene

noun

mass noun
  • A form of carbon consisting of planar sheets which are one atom thick, with the atoms arranged in a honeycomb-shaped lattice.

    • ‘Graphite has a crystal structure consisting of many one-atom-thick carbon sheets known as graphene.’
    • ‘Known as graphene, the new fabric effectively exists in just two dimensions, and could pave the way for computers built from single molecules.’
    • ‘The electronic properties of a carbon nanotube, for example, depend on its chirality, which, in turn, depends on the direction in which the graphene sheet has been rolled up to form the nanotube.’
    • ‘Carbon nanotubes are rolled up sheets of graphene just a few nanometres in diameter that can behave as either metals or semiconductors depending on their atomic arrangement.’
    • ‘So if your local network broadcast pulses in the infrared, these fibers could act as both detectors and displays, while the graphene above could handle the computations to transform one to the other.’

Origin

1980s: blend of graphite and -ene (sense 2).
