Graphene consists of carbon atoms arrayed in a hexagonal pattern in a large sheet. Layers of graphene constitute graphite, the familiar "lead" in pencils. Nanotubes are, in a sense, tubular graphene. Electrons can very easily travel along the carbon sheet making graphene an extremely good electrical conductor. This conductivity suggests that graphene could have a future in the semiconductor industry, with the fabrication of high speed transistors. The carbon atoms are shown as spheres drawn at their covalent radius (i.e. just touching). Images on thie page are 500 pixels across, the originals are 4096 pixels across. |
