Study Of Carbon Nanotubes Structures And Its Properties For Sensor Applications

Carbon nanotubes are attractive for nanoelectronic sensor applications due to its excellent electric properties and sensitivity. In this paper we studied the property of carbon nanotubes, types and its modes, we study the carbon nanotube characteristics under the chirality vector of 9,9; 6,0; 2,9. By studying this mode we can able to choose the appropriate chirality vector for choosing the carbon nanotubes to the desired applications. CNT are used in field effect transistor for different sensor applications mainly in biomedical field. By the advancement of VLSI and CNT, the sensitivity, performance, response time can be improved.
