Electronic properties of Carbon Nanotubes
4 November 2007Carbon nanotubes were first produced in the year 1991 and since then various studies has been carried out on these carbon nanotubes. These carbon nanotubes find promising applications in the area of molecular electronics. These now are explored as the building blocks in the fabrication of electronic devices.
The carbon nanotube have especially a molecular level arrangement making these suitable to develop best alternative of silicone based IC at the nanometer scale. These carbon nanotubes are known for the stiffness making these suitable for electronic applications.
In single wall carbon nanotubes at low temperature, the electronic waves may remain extended along the nanotube over several microns. This shows that the motion of electron is quantum mechanical in nature.
Scientists look for the methods of designing nanotechnology devices to tailor the molecular structures to achieve given functionality. Scientists have already explored construction of some of the electronic devices such as diodes, logic circuits, memory elements and transistors.
