IBM claims breakthrough on carbon nanotubes

One of the leading candidates to replace silicon CMOS transistors is carbon nanotubes. But there are still lots of issues with both the basic materials and device structure. Now IBM says it has solved one of the big ones.

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?

What is graphene?

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

A one-atom thick billiard table

A team of physicists at the University of California at Riverside (UCR) have found that graphene, which was isolated experimentally only less than three years ago, and which is a one-atom thick sheet of carbon atoms arranged in hexagonal rings, can act as an atomic-scale billiard table. They found that electrons in graphene behave like quantum billiard balls. This research could lead to new kinds of transistors based on quantum physics. In fact, it's possible that graphene can replace silicon as the basic electronic material in a few years. For example, it could be used to develop 'ballistic' transistors.

Nanotubes: The stuff of dreams

They are stronger than steel and as flexible as plastic, conduct energy amazingly well and can be made from unexotic raw materials. But can nanotubes live up to their promise?
