Phd thesis carbon nanotubes

DescriptionIt is well known that carbon nanotubes CNT exhibit remarkable electrical, mechanical and optical properties. In addition, conducting polymers have also been used for molecular sensors, electronic energy generation and storage devices due to their interesting electronic and electrochemical properties. Blending pre-formed polymers with carbon nanotubes has been demonstrated to be the most straightforward approach to fabricate carbon nanotube composites.

Phd thesis carbon nanotubes

May 31, Faster computers with nanotechnology Nanowerk News The silicon transistors in your computer may be replaced in ten years by transistors based on carbon nanotubes.

Silicon is subject to certain limitations, and industry is looking for a replacement. The electronics industry has net annual sales of over USD billion, and this means that the development is being fuelled by powerful forces.

Johannes Svensson the author of the thesis, Carbon Nanotube Transistors: The amazing development in computer power that has taken place after the invention of the integrated circuit in the s has been made possible by the transistor, which is the most important component of all processors, becoming ever-faster.

The most common semiconductor material in transistors is silicon, since it is cheap and easy to process. But silicon has its limitations. As the size of the transistors is reduced in order to increase their speed, problems arise that lead to, among other things, increased energy consumption and large variation in the transistor properties.

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

Choosing the correct diameter will allow good contacts with a low resistance to be achieved. The thesis Carbon Nanotube Transistors:Interaction between carbon nanotubes and their physico-chemical environment: towards the control of the optical properties - Vialla, Fabien (), Phd thesis OPTO.
