One-Atom-Thick Cloth Developed For 21st Century Bikinis

In the quest to make the computer chip more powerful and fast, engineers strive to produce smaller transistors, shortening the paths electrons have to travel to switch the devices on and off. Ultimately, scientists envisage transistors made from a single molecule, and this work brings that vision ever nearer.

In terms of applications, the sort of quality demonstrated by graphene can only be compared with that demonstrated by some nanotubes. Professor Geim commented: “As carbon nanotubes are basically made from rolled-up narrow stripes of graphene, any of the thousands of applications currently considered for nanotubes renowned for their unique properties can also apply to graphene itself.”

Although the researchers are currently dealing with patches of graphene that are about ten microns across, Professor Geim commented: “Computer engineers will need graphene wafers a few inches in size, before considering graphene as “the next big thing.” However, all the omens are good, as there are no fundamental limitations on the lateral size of carbon nanofabric.” Dr Novoselov added: “Only ten years ago carbon nanotubes were less than a micron long. Now, scientists can make nanotubes several centimetres long, and similar progress can reasonably be expected for carbon nanofabric too.”

David Glover from University of Manchester Intellectual Property Ltd commented: “This is clearly an exciting breakthrough with huge potential, and with development graphene could soon compete in many niche markets where low energy consumption and high electron mobility are paramount requirements.”
