Field-effect transistor (FET) behavior was observed by scanning tunneling microscopy (STM) for a single-walled carbon nanotube curled over parallel Au lines, with the STM acting as a gate electrode [140]. 

The other interesting material for electronics is carbon nanotubes. We have shown the application of individual single-walled carbon nanotubes for field effect transistors (FETs) [3]. Carbon nanotubes (CNT) or CNT bundles can be placed between two carbon electrodes playing the role of source and drain. The gate electrode can be made of thin metal stripe under the dielectric film in the region between source and drain.

Siwy et al. demonstrated the utility of a single conically shaped gold nanotube that was embedded in a mechanically and chemically robust polymeric membrane [142]. They reported biofunctionalized conical Au nanotubes, which are potentially useful for obtaining highly sensitive and selective protein biosensors. So et al. introduced a single walled carbon nanotube field effect transistor (SWNT-FET) combined with aptamers as an alternative to the corresponding antibody [143].

Abstract This chapter focuses on the performances of gas sensors based on single-walled carbon nanotubes (SWCNTs).The chapter first reviews chemiresistor and field-effect transistor sensor architectures. Theoretical models based on doping effect and Schottky barrier modulation are correlated to the percolation of metallic carbon nanotubes. The functionalisation strategies of carbon nanotubes, used to acquire a gas selectivity, are discussed and offer promising application for the monitoring of air quality, or military and medical applications.

On the other hand, a nanoparticle enhancement approach has been described by Dong et al. [71] to improve the detection sensitivity of field-effect transistors based on single-walled carbon nanotube networks (SNFETs). Figure 4.12 shows as the target DNA was hybridized with probe DNA on the device, reporter DNA labeled with Au-NPs flank a segment of the target DNA sequence. The amplified change in drain current allowed a DNA concentration down to 100 fM to be detected. 

Template-synthesized polymers [143,144] are expected to have applications in miCToelectronics, dmg delivery, bioencapsulation, ultratrace chemical analysis and second-order tanplates for the growth of other nanoarrays. Carbon nanotube electronics are expected to provide a viable alternative to silicon. The development of an array of transistors using carbon nanotubes and the development of computer circuits using single-walled carbon nanotube was recently reported by IBM [ 145]. Carbon nanotubes also find use as cold cathode flat panel display [146]. Carbon nanotubes can also be used to encapsulate [147] other materials like Fe and Co. Well-ordered carbon nanotubes have been synthesized [148-150] in nanoporous alumina m brane template.
