High Value Semiconducting Carbon Nanotubes

12.07.2004


Moore’s Law states that the number of transistors on a chip doubles every eighteen months. However current silicon technologies are approaching the limits imposed by quantum mechanics, which will stop Moore’s Law in its tracks within 20 years. New materials and techniques must be found to complement and increase the capabilities of the current silicon technologies to maintain the growth and profitability of the semi-conductor industry.

Semiconducting carbon nanotubes can be doped like silicon, and are one of the best candidate materials for replacing current semiconductors. A nanotube is about 1/500th the size of a current transistor and has excellent electrical properties. However, current production methods create a mixture of nanotubes with both semiconducting and metallic properties that makes them expensive and difficult to use. A simple method for producing clean, well-dispersed, high purity semiconducting carbon nanotubes would have significant commercial benefits.

The Oxford Invention is a technique for purifying samples of carbon nanotubes to remove both general metallic and graphitic contamination. A product containing more than 90% semiconducting nanotubes can already be produced, and further increases in the proportion of semiconducting nanotubes in the final product are expected as development continues. The technology can be used for both single-walled nanotubes and multi-walled nanotubes.



The technology is the subject of a Patent Application and is available for licensing. Isis would like to talk to companies interested in exploiting the commercial opportunity that this breakthrough represents.

Im Focus: Data storage using individual molecules

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.

Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...

Im Focus: Data use draining your battery? Tiny device to speed up memory while also saving power

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

Im Focus: An energy-efficient way to stay warm: Sew high-tech heating patches to your clothes

Personal patches could reduce energy waste in buildings, Rutgers-led study says

What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
