Abstract

From its discovery in 2004 to a Nobel Prize in 2010 for Novosolev and Geim, the rise of graphene has been nothing short of spectacular, and in combination with its close relative, the carbon nanotube, its range of amazing properties is revolutionizing a wide range of science and technology. Graphene is a metal with controllable densities of electrons and holes both of which act like massless charged particles moving relativistically, even at room temperature. As a result they have quantized resistance and optical transmission and the high electron velocity offers the potential for super high speed electronics. All which was discovered using Scotch tape and a piece of pencil lead! Large area sheets of graphene can now be made and can be used as transparent electrodes for touch screens and photovoltaic cells and Wafer scale electronics now looks possible.

Rolling the graphene up into carbon nanotubes can turn the tubes into semiconductors producing new properties, opening up another range of potential applications and novel properties. This covers areas from electronics to high strength materials, while combining them with polymer semiconductors produces new nano-hybrids with the potential to make improved solar cells.
