New wonder material, one-atom thick, has scientists abuzz

Imagine a carbon sheet that's only one atom thick but is stronger than diamond and conducts electricity 100 times faster than the silicon in computer chips. That's graphene, the latest wonder material coming out of science laboratories around the world. It's creating tremendous buzz among physicists, chemists and electronic engineers.

"It is the thinnest known material in the universe, and the strongest ever measured," Andre Geim, a physicist at the University of Manchester, England, wrote in the June 19 issue of the journal Science.

"A few grams could cover a football field," said Rod Ruoff, a graphene researcher at the University of Texas, Austin, in an e-mail. A gram is about 1/30th of an ounce.

Like diamond, graphene is pure carbon. It forms a six-sided mesh of atoms that, through an electron microscope, looks like a honeycomb or piece of chicken wire. Despite its strength, it's as flexible as plastic wrap and can be bent, folded or rolled up like a scroll.

Graphite, the lead in a pencil, is made of stacks of graphene layers. Although each individual layer is tough, the bonds between them are weak, so they slip off easily and leave a dark mark when you write.

Potential graphene applications include touch screens, solar cells, energy storage devices, cell phones and, eventually, high-speed computer chips.

Replacing silicon, the basic electronic material in computer chips, however, "is a long way off ... far beyond the horizon," said Geim, who first discovered how to produce graphene five years ago.

"In the near- and medium-term, it's going to be extremely difficult for graphene to displace silicon as the main material in computer electronics," said Tomas Palacios, a graphene researcher at the Massachusetts Institute of Technology. "Silicon is a multibillion-dollar industry that has been perfecting silicon processing for 40 years."

Government and university laboratories, long-established companies such as IBM, and small start-ups are working to solve difficult problems in making graphene and turning it into useful products.

Ruoff founded a company in Austin called Graphene Energy, which is seeking ways to store renewable energy from solar cells or the energy captured from braking in autos.

The Pentagon is also interested in this new high-tech material. The Defense Advanced Research Projects Agency is spending $22 million on research to make computer chips and transistors out of graphene.

Graphene was the leading topic at the annual meeting of the American Physical Society _ a leading organization of physicists _ in Pittsburgh in April. Researchers packed 23 panel sessions on the topic. About 1,500 scientific papers on graphene were published in 2008 alone.

Until last year, the only way to make graphene was to mount flakes of graphite on sticky tape and separate a single layer by carefully peeling away the tape. They called it the "Scotch Tape technique."

Recently, however, scientists have discovered a more efficient way to produce graphene on an underlying base of copper, nickel or silicon, which subsequently is etched away.

"There has been spectacular progress in the last two or three months," Geim reported in the journal Science. "Challenges that looked so daunting just two years ago have suddenly shrunk, if not evaporated."

"I'm confident there will be many commercial applications," Ruoff said. "We will begin to see hybrid devices -- mostly made from silicon, but with a critical part of the device being graphene -- in niche applications."

How sticky tape trick led to Nobel Prize

BBC News Science & Environment, by Paul Rincon Science reporter, BBC News

It sounds like an unusual way to win a Nobel Prize. But ordinary sticky tape was crucial to the breakthrough that yielded graphene, a material with amazing properties and - potentially - numerous practical applications.

The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics for 2010 to Andre Geim University of Manchester, UK and Konstantin Novoselov University of Manchester, UK

"for groundbreaking experiments regarding the two-dimensional material graphene"

Graphene – the perfect atomic lattice

A thin flake of ordinary carbon, just one atom thick, lies behind this year’s Nobel Prize in Physics. Andre Geim and Konstantin Novoselov have shown that carbon in such a flat form has exceptional properties that originate from the remarkable world of quantum physics.

Graphene is a form of carbon. As a material it is completely new – not only the thinnest ever but also the strongest. As a conductor of electricity it performs as well as copper. As a conductor of heat it outperforms all other known materials. It is almost completely transparent, yet so dense that not even helium, the smallest gas atom, can pass through it. Carbon, the basis of all known life on earth, has surprised us once again.

Geim and Novoselov extracted the graphene from a piece of graphite such as is found in ordinary pencils. Using regular adhesive tape they managed to obtain a flake of carbon with a thickness of just one atom. This at a time when many believed it was impossible for such thin crystalline materials to be stable.

However, with graphene, physicists can now study a new class of two-dimensional materials with unique properties. Graphene makes experiments possible that give new twists to the phenomena in quantum physics. Also a vast variety of practical applications now appear possible including the creation of new materials and the manufacture of innovative electronics. Graphene transistors are predicted to be substantially faster than today’s silicon transistors and result in more efficient computers.

Since it is practically transparent and a good conductor, graphene is suitable for producing transparent touch screens, light panels, and maybe even solar cells.

When mixed into plastics, graphene can turn them into conductors of electricity while making them more heat resistant and mechanically robust. This resilience can be utilised in new super strong materials, which are also thin, elastic and lightweight. In the future, satellites, airplanes, and cars could be manufactured out of the new composite materials.

This year’s Laureates have been working together for a long time now. Konstantin Novoselov, 36, first worked with Andre Geim, 51, as a PhD-student in the Netherlands. He subsequently followed Geim to the United Kingdom. Both of them originally studied and began their careers as physicists in Russia. Now they are both professors at the University of Manchester.

Playfulness is one of their hallmarks, one always learns something in the process and, who knows, you may even hit the jackpot. Like now when they, with graphene, write themselves into the annals of science. Read more about this year's prize


(Wikipedia, the free encyclopedia)

Graphene is an atomic-scale honeycomb lattice made of carbon atoms.
Graphene is an allotrope of carbon, whose structure is one-atom-thick planar sheets of sp2-bonded carbon atoms that are densely packed in a honeycomb crystal lattice.[1] The term graphene was coined as a combination of graphite and the suffix -ene by Hanns-Peter Boehm,[2] who described single-layer carbon foils in 1962.[3] Graphene is most easily visualized as an atomic-scale chicken wire made of carbon atoms and their bonds. The crystalline or "flake" form of graphite consists of many graphene sheets stacked together.

The carbon-carbon bond length in graphene is about 0.142 nanometers.[4] Graphene sheets stack to form graphite with an interplanar spacing of 0.335 nm, which means that a stack of three million sheets would be only one millimeter thick. Graphene is the basic structural element of some carbon allotropes including graphite, charcoal, carbon nanotubes and fullerenes. It can also be considered as an indefinitely large aromatic molecule, the limiting case of the family of flat polycyclic aromatic hydrocarbons.
