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.

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.
Silicene could revolutionise electronics and even be more exciting than graphene - although reseachers will have to figure out exactly what it is, first.
IBM has revealed three new developments that aim to power tomorrow's digital technology. Based on nanotubes, nanowires and graphene, their common factor is compatibility with today's production techniques
Swiss researchers have made a prototype microchip using a substance called molybdenite, which could prove to be a rival to both silicon and graphene
Chancellor George Osborne has announced a £5bn National Infrastructure Plan, including funding to create up to 10'super-connected cities'
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.
In the latest round of graphene discoveries, researchers are finding that graphene can respond to light and be built to replace the silicon chip.
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
When first discovered, graphene was odd. Now odd is too small a word for a material seemingly set on winning all the records a material can win
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.
Sellotape and sugar rub shoulders with high-temperature furnaces and low-pressure chambers in a rush to produce graphene, which aims to be the 21st century's successor to silicon
Researchers at the University of California, Berkeley, have created a graphene-based optical modulator that they think could lead to digital communications up to 10 times faster than is possible with currently-deployed technology.Graphene is a one-atom thick layer of crystallised carbon that many hope will overcome the limitations of silicon and lead to viable quantum computing.
IBM has demonstrated a new super whizzy graphene transistor, clocking in at 155GHz, up from the 100GHz it benched last year.The breakthrough was made possible because the transistor was set on a substrate of "diamond-like carbon", itself layered on a commercial silicon wafer.
This week, IBM began something of a band-gap backlash against wunder material graphene. After the computer firm said graphene would never fully replace silicon, a group of scientists in Switzerland announced that there was another two dimensional industrial lubricant with more traditional semi-conductor properties – molybdenum - that could send silicon into retirement.
Watch out graphene. Just a week after IBM said the two dimensional wonder-carbon would never fully replace silicon, graphene has yet more competition.
