So-called 'wonder material' graphene may be many things, but a replacement for silicon? Not so much, says the head of the graphene flagship that won €1bn in funding last month.
Carbon nanotubes may take over from silicon as processors get smaller and more energy-efficient, and IBM has just announced a fresh breakthrough in making the technology viable.
Researchers' creation of a silicon-based field-effect transistor that mimics the electrical properties of graphene shows the battle for the future of electronics is still on.
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 might be stealing all the headlines, but other forms of carbon are still making waves in the emerging field of spintronics.So says researcher Michel de Jong, based at the University of Twente in the Netherlands.
Researchers at Manchester University – spiritual home of graphene – have now discovered how to magnetise the wonder-material. Yes, you read that right: they have magnetised carbon.
Swiss researchers have made a prototype microchip using a substance called molybdenite, which could prove to be a rival to both silicon and graphene
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.
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.
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.
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.
Rice University scientists demonstrate how graphene -- a "miracle material" -- can be made from just about any carbon source, including insects, waste, and Girl Scout cookies.
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.
We talk a lot about graphene, on this blog. The wonderful two dimensional lattice of carbon with its hexagonal, chickenwire structure.
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.
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?
Graphene gets its unique properties from the geometry of its carbon atoms. But how does something so simple produce such profoundly different physics?
Researchers at IBM have succeeded in creating a complete high-speed integrated circuit made from by depositing multiple layers of graphene on a silicon wafer
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.
