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.
The Manchester University team that first isolated graphene has discovered a way of introducing a band gap into the material that makes it a much more promising candidate for building transistors.Graphene is famous for its astonishing list of useful characteristics – especially its conductivity.
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
The world gets cooler by the day. Yet another of graphene’s unusual properties – this time its stretchiness – has brought it to the fore, as a team of researchers in South Korea have used the material to build stretchable transistors.
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.
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
Carbon is valuable as diamond and in oil, but a new form of the pure element may be even more important in our future. ZDNet UK presents the first in a series of features on graphene
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.
Swiss physicists throw another, more energy efficient, material into the ring as a potential silicon substitute: molybdenite.
In an about-face move, IBM has revealed that graphene can't fully replace silicon inside CPUs reports Bit-tech, a UK-based hardware enthusiast site. The reason? A graphene transistor can't actually be completely switched off.
Researchers at Rice University and the University of California, Riverside have taken advantage of another quirk in graphene's arsenal, ambipolarity, to build and test a triple mode transistor, that could lead to yet smaller and cooler (not in the iPod sense) wireless devices.Conventionally, ability of a transistor to conduct either electrons (negative charge) or holes (positive charge) is fixed during fabrication.
Scientists in the US have found a way of growing graphene on etched silicon carbide, producing the highest ever density of graphene transistors: an array of 10,000 top-gated transistors on a .24cm square chip.
The University of Manchester's Andre Geim and Konstantin Novoselov have won the physics prize for their work on graphene, which is widely seen as a successor to silicon in electronics
We know graphene is the best thing since sliced gallium arsenide to hit the electronics industry, thanks to the speed with which it dispatches electrons across its famous chickenwire network of carbon atoms. But so far, making transistors from the stuff live up to the promise it holds has been problematic.
IBM Research plans to announce that it has demoed a radio-frequency graphene transistor with the highest frequency so far
IBM Research has demonstrated a radio-frequency graphene transistor with the highest frequency (100 GigaHertz) so far.
