The Field Effect Transistor using nanotechnology is known as Carbon Nanotube Field Effect Transistors (CNTFET). Which promising nano-scaled devices for implementing high performance very dense and low power circuits. A Carbon Nanotube Field Effect Transistor refers to a FET with a single CNT or an array of CNT's as the channel material instead of bulk silicon in the traditional MOSFET structure...

Carbon nanotubes (CNTs) and carbon nanotube field effect transistors (CNFETs) have demonstrated extraordinary properties and are widely expected to be the building blocks of next generation VLSI circuits. This chapter presents (1) the first purely CNT and CNFET based nanoarchitecture, (2) an adaptive configuration methodology for nanoelectronic design based on the CNT nano-architecture, and (3)...

We demonstrate a 1.2-GHz repetition rate, diode-pumped, self-starting, 168-fs (FWHM) pulsewidth Yb:KYW laser mode-locked by a carbon nanotube (CNT) saturable absorber mirror. To our knowledge, this result corresponds to the highest repetition rate from CNT-mode-locked femtosecond bulk solid-state lasers, reaching the GHz regime for the first time.

A previously overlooked step of carbon nanotube (CNT) growth, incorporating C atoms into the CNT wall through the CNT-catalyst interface, is studied by density functional theory calculations. A significant barrier for incorporating C atoms into the CNT wall (∼2  eV for most used catalysts, Fe, Co, and Ni) is revealed and the incorporation can be the threshold step of CNT growth in most experime...

The electrical and mechanical characteristics of composite materials prepared using evaporative casting and vacuum filtration of carbon nanotubes (CNTs) dispersed in the biopolymer s-carrageenan (IC) are reported. It is demonstrated that the contact angle of water with films is proportional to the CNT mass and volume fraction, which is used to compare the properties of buckypapers with those of...

Abstract This chapter presents the unique atomic structure and properties of carbon nanotube (CNT). The electronic band structure of carbon nanotube along with their small size and low dimension are responsible for their unique electrical, mechanical, and thermal properties. This chapter summarizes the electronic band structure of one-dimensional CNTs, various transport properties, and their re...

A biocathode was designed by the modification of a carbon nanotube (CNT) gas-diffusion electrode with bilirubin oxidase from Bacillus pumilus, achieving high current densities up to 3 mA cm(-2) for the reduction of O2 from air. A membraneless air-breathing hydrogen biofuel cell was designed by combination of this cathode with a functionalized CNT-based hydrogenase anode.

A novel strategy for designing ultrathin polypyrrole skin-coated carbon nanotube (CNT) nanohybrids is demonstrated by vapor deposition polymerization (VDP). The ultrathin skin technology provides a stable immobilization of the mono-disperse Pd nanoparticles (NPs) on the CP-CNT nanohybrid surface, leading to a high-performance hydrogen gas sensor at room temperature.

Electron emission from the sidewall of a bent individual multiwall carbon nanotube (CNT) is reported. The CNT was synthesized using a catalytic chemical vapor deposition method and the focused-ion beam technique was used to fabricate the CNT-based electron emitter. With controlled ion bombardment, individual carbon nanotubes can be bent into loops with different radii. An external electric fiel...
