Samsung touts process to commercialize graphene

Samsung's new process to synthesize graphene---a form of carbon more durable than steel and flexible for use in displays and wearables---could apply broadly to its product lineup over time.

Graphene research: shear forces to sheer displays

Lab tests have confirmed theoretical predictions about the shear and strain that single sheets of graphene can withstand, bringing industrial and commercial applications of the material a step closer.The two-dimensional, hexagonal lattice of carbon has piqued the interest of display and solar cell manufacturers because of its transparency and high conductivity.

Graphene ribbons to replace copper on chips?

Not content with taking on the might of silicon, now graphene in all its two-dimensional glory is giving the evil eye to copper. According to an announcement from Rensselaer Polytechnic Institute, graphene is a promising candidate to replace copper as the size of circuitry on chips shrinks ever smaller.

Batteries boosted with silicon-graphene layers

Researchers have found a way to make lithium ion batteries hold a charge ten times greater than they do at present, and charge ten times faster. To do this they have had to overcome some limitations of wonder-material graphene.

Researchers shed light on photoelectricity in graphene

Graphene has revealed yet more interesting characteristics, as researchers in the US investigate the way the two-dimensional form of carbon reacts to light. Regular readers will not be surprised to learn that it differs a little from a typical semi-conductor.

Osborne puts £50m into UK graphene research

Chancellor George Osborne has promised £50 million for research into graphene, the carbon-based material tipped as a breakthrough in material science, nanotechnology and electronics.Graphene was discovered in 2004 by Dr (now Professor) Kostya Novoselov and Professor Andre Geim from the University of Manchester in work that won them the 2010 Nobel Prize for physics.

For orderly graphene sheets, just add Hydrogen

Researchers have known for some time that the quality of graphene produced by vapour deposition depends on a number of factors: the carbon source and the substrate material being major players.However, scientists at the US Department of Energy’s National Laboratory in Oak Ridge have found that hydrogen plays a much more active role in the formation of the material than previously thought.

Lasers could illuminate band gap for graphene

Graphene: famous for being a Nobel Prize prompting wonder material, and for having no band gap. The lack of band gap means graphene’s future as a possible replacement for silicon has always looked bleak, because a band gap is the property that allows a transistor to be switched on and off.

The future of graphene

Graphene hints at a world of electronics beyond silicon, unshackled from Moore's Law. What can we expect from this wonder material over the next 10 years?

How does graphene work?

Graphene gets its unique properties from the geometry of its carbon atoms. But how does something so simple produce such profoundly different physics?

Transistors? Pah. IBM demos complete graphene circuit

IBM, having wowed us all in April with graphene transistors that run at 155GHz, has gone one step further and now reports success in building a high-speed, graphene-based circuit.The researchers, writing in the June 10 issue of Science, describe how they deposited multiple layers of graphene on a silicon wafer.
