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.
Hybrid interconnects that employ CNT vias in tandem with copper interconnects may offer advantages in reliability and thermal-management. [5] In 2016, the European Union has funded a four million euro project over three years to evaluate manufacturability and performance of composite interconnects employing both CNT and copper interconnects.
CNT lengths range from less than 100 nm to 0.5 m. [1] Individual CNT walls can be metallic or semiconducting depending on the orientation of the lattice with respect to the tube axis, which is called chirality. MWNT's cross-sectional area offers an elastic modulus approaching 1 TPa and a tensile strength of 100 GPa, over 10-fold higher than any ...
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 ...
The Confederación Nacional del Trabajo (CNT) (National Confederation of Labor) is a Spanish anarcho-syndicalist trade union confederation.. Founded in 1910 in Barcelona from groups brought together by the trade union Solidaridad Obrera, it significantly expanded the role of anarchism in Spain, which can be traced to the creation of the Spanish chapter of the IWA in 1870 and its successor ...
As figure 3.1 shows, the nanomotor consists of a double-walled CNT (DWNT) formed from an achiral (18,0) outer tube clamped to external gold electrodes and a narrower chiral (6,4) inner tube. The central portion of the outer tube is removed using the electrical-breakdown technique to expose the free-to-rotate, inner tube. The nanodrill also ...
CNT was founded on March 15, 1979 by entrepreneur and politician José Carlos Martinez as a local station called TV Tropical, originally affiliated to Rede Globo until it was sold to Diários Associados in 1980. In 1982, the station was renamed as Rede OM, and was subsequently renamed as CNT in 1993 after becoming a national network the ...
The CNT QD connected to metallic leads constitutes a genuine many-body system, due to the electron correlations. Therefore, Wilson's Numerical renormalization group is often used to study the CNT QD. The CNT QD is modelled as an Anderson-type model, which can be reduced by Schrieffer-Wolff transformation to an effective Kondo-type model at low ...
