A single walled carbon nanotube (SWCNT)-based three-electrode system was fully integrated on glass substrates using a standard microfabrication process and electrochemically characterized using cyclic voltammetry. O(2) plasma functionalization of the SWCNT film working electrode for achieving high sensitivity was voltammetrically optimized with respect to the plasma power and treatment time. Ch...

In this Letter, we demonstrate thin-film single-walled carbon nanotube (SWCNT) complementary metal-oxide-semiconductor (CMOS) logic devices with subnanowatt static power consumption and full rail-to-rail voltage transfer characteristics as is required for logic gate cascading. These results are enabled by a local metal gate structure that achieves enhancement-mode p-type and n-type SWCNT thin-f...

Based on the theories of thermal elasticity mechanics and nonlocal elasticity, an elastic Bernoulli–Euler beam model is developed for thermal-mechanical vibration and buckling instability of a single-walled carbon nanotube (SWCNT) conveying fluid and resting on an elastic medium. The finite element method is adopted to obtain the numerical solutions to the model. The effects of temperature chan...

The goal of this research was to develop a chemical gas sensing device based on single-walled carbon nanotube (SWCNT) networks. The SWCNT networks are synthesized on Al(2)O(3)-deposted SiO(2)/Si substrates with 10 nm-thick Fe as the catalyst precursor layer using microwave plasma chemical vapor deposition (MPCVD). The development of interconnected SWCNT networks can be exploited to recognize th...

Chemical Functionalization is a technique used to increase the dispersion and solubility of single-walled carbon nanotube (SWCNT). Functionalization of a (10, 0) zigzag nanotube segment containing 80 C atoms was investigated with the aide of spinunrestricted density functional theory (DFT). The (10, 0) was funtionalized with three organic acid groups: (a) carboxylic acid, (b) aromatic dicarboxy...

The adsorption of a number of amino acids on a defected single-walled carbon nanotube (SWCNT) isinvestigated by using the density-functional theory (DFT) calculations. The adsorption energies andequilibrium distances are calculated for various configurations such as amino acid attaching to defectsites heptagon, pentagon and hexagon in defective tube and also for several molecular orientationswi...

It has been found that multiwalled carbon nanotubes (CS-CNT) can be produced in mass level, simply by pyrolysing mustard oil which was then derivatized with carboxylic acid (CS-CNT (acid)) and ammonia (CS-CNT (base)). A low cost electrode was fabricated on Teflon substrate with three silver wires which was coated with different types of carbon nanotube. A comparative study of electrochemical be...

High performance single-walled carbon nanotube field effect transistors SWCNT-FETs fabricated with thin atomic layer deposited ALD Al2O3 as gate dielectrics and passivation layer are demonstrated.
