Faster computers with nanotechnology

e carbon. Some carbon nanotubes are semiconducting, and this means that they can be used in transistors, although there are several problems that must be solved before they can be connected together to form large circuits.

Electric guidance

"Carbon nanotubes grow randomly and it is not possible to control either their position or direction. Therefore I have applied an electrical field to guide the tubes as they grow", says Johannes Svensson.

Built his own

One of the effects of the electric field is that most of the carbon nanotubes lie in the same direction.

"In order to show that it is possible to build electronic components that contain only carbon nanotubes, I have built a transistor which not only has a carbon nanotube as its channel, but also another nanotube which is used as the electrode that controls the current."

Good contacts

Another problem that must be solved when integrating nanotubes into larger circuits is the difficulty of manufacturing good metal contacts for the tubes. Johannes' research has shown that the properties of the contacts depend on the diameter of the nanotubes. Choosing the correct diameter will allow good contacts with a low resistance to be achieved.
