Breakthrough in Developing Super-Material Graphene
A collaborative research project has brought the world a step closer to producing a new material on which future nanotechnology could be based. Researchers across Europe, including the UK's National Physical Laboratory (NPL), have demonstrated how an incredible material, graphene, could hold the key to the future of high-speed electronics, such as micro-chips and touchscreen technology.
Graphene has long shown potential, but has previously only been produced on a very small scale, limiting how well it could be measured, understood and developed. A pa-per published on the 17th January, in Nature Nanotechnology explains how researchers have, for the first time, produced graphene to a size and quality where it can be practically developed, and successfully measured its electrical characteristics. These significant breakthroughs overcome two of the biggest barriers to scaling up the technology.

Graphene, only one atom thick, climbs terraces on the su**ce of a silicone carbide substrate. This picture of a graphene device was taken with an atomic force microscope.

A technology for the future

Graphene is a relatively new form of carbon made up of a single layer of atoms arranged in a honeycomb shaped lattice. Despite being one atom thick and chemically sim-ple, graphene's is extremely strong and highly conductive, ma-king it ideal for high-speed electronics, photonics and beyond.
Graphene is a strong candidate to replace semiconductor chips. Moore's Law observes that the density of transistors on an integrated circuit doubles every two years, but silicon and other existing transistor materials are thought to be close to the minimum size where they can remain effective. Graphene transistors can potentially run at faster speeds and cope with higher temperatures. Graphene could be the solution to ensuring computing technology to continue to grow in power whilst shrinking in size, extending the life of Moore's law by many years.
Large microchip manufacturers such as IBM and Intel have openly expressed interest in the potential of graphene as a material on which future computing could be based.
Graphene also has potential for exciting new innovations such as touchscreen technology, LCD displays and solar cells. Its unparalleled strength and transparency make it perfect for these applications, and its conductivity would offers a dramatic increase in efficiency on existing materials.
