A carbon nanotube field-effect transistor (CNTFET) is a field-effect transistor that utilizes a single carbon nanotube (CNT) or an array of carbon nanotubes as the channel material, instead of bulk silicon, as in the traditional MOSFET structure. There have been major developments since CNTFETs were first demonstrated in 1998. [1] [2]
Further studies, such as one conducted in 2008, revealed that individual CNT shells have strengths of up to ≈100 gigapascals (15,000,000 psi), which is in agreement with quantum/atomistic models. Since carbon nanotubes have a low density for a solid of 1.3 to 1.4 g/cm 3 , its specific strength of up to 48,000 kN·m·kg −1 is the best of ...
Covalent modification attaches a functional group onto the carbon nanotube. The functional groups can be attached onto the side wall or ends of the carbon nanotube. [ 6 ] The end caps of the carbon nanotubes have the highest reactivity due to its higher pyramidization angle and the walls of the carbon nanotubes have lower pyramidization angles ...
A carbon nanotube (CNT) is a tube made of carbon with a diameter in the nanometre range . They are one of the allotropes of carbon. Two broad classes of carbon nanotubes are recognized: Single-walled carbon nanotubes (SWCNTs) have diameters around 0.5–2.0 nanometres, about 100,000
The catalyst particles obtained by laser ablation of a cobalt target sorted by size ultimately allow to grow a CNT density around 10 12 CNT cm −2 using a multistep process using plasma and catalyst particles around 4 nm. In spite of these efforts, the electrical resistance of such via is 34 Ω _for a 160 nm diameter.
CNT can be filled with biological molecules, aiding biotechnology. [citation needed] CNT have the potential to store between 4.2 and 65% hydrogen by weight. If they can be mass-produced economically, 13.2 litres (2.9 imp gal; 3.5 US gal) of CNT could contain the same amount of energy as a 50 litres (11 imp gal; 13 US gal) gasoline tank.
