“…This is possible as the cross-section of momentum transfer from Ga ions to carbon atoms is quite high [14]. These studies show that the density of defects can be reduced and higher crystallinity achieved under ion irradiation, whereas another studies reported amorphisation or defects introduction during irraditiation of CNTs [14][15][16][17]. This difference can be attributed probably to different conditions of the experiments (the density of defects before irradiation, the dose applied, etc.).…”

A method of ac dielectrophoresis was applied to align and deposit metallic multi-wall carbon nanotubes between pre-fabricated metal (Au, Pd) electrodes with a micron scale separation. For improvement of nanotube contacts with electrodes, Ni and Pd electroless processes were developed, and significant reduction of 2 terminals resistances was demonstrated. Further, using electron and ion beam deposited Pt contacts in two different configurations (“Pt-on-CNT” and “CNT-on-Pt”), 4 terminals measurements have been performed to evaluate intrinsic nanotube resistances. The values between 90 and 130 kΩ/μm were obtained, while systematically lower values (30-70 kΩ/μm) were estimated using 2 terminals method. The 4 terminals method was applied to study the effect of ion irradiation on the electrical parameters of supported nanotubes.

Multi-walled carbon nanotubes (CNTs) were grown via pyrolytic chemical vapor deposition technique and explored for their infrared sensing behavior. CNT synthesis was carried out over cobalt zinc ferrite (Co 0.5 Zn 0.5 Fe 2 O 4 ) catalyst nanoparticles under different gas flow conditions to control outside diameter of the nanotubes. It was found that a progressive decrease in the carbon precursor gas (acetylene in this case) from 5:1 to 9:1 (v/v) causes reduction of average CNT diameter from 85 nm to 635 nm. Growth conditions involving higher temperatures yield nanotubes/nanofibers with outer diameter of > 500 nm, presumably due to surface aggregation of nanoparticles or increased flux of carbonaceous species at the catalyst surface or both. Current-voltage characteristics of the nanotubes depending on the CNT diameter, revealed linear or nonlinear behavior. When incorporated as sensing layer, the sensitivity of ∼ 5.3 was noticed with response time of ∼ 4.1 s. It is believed that IR sensing characteristics of such CNT-based detectors can be further enhanced through post-synthesis purification and chemical functionalization treatments.

Jet stream: Multi‐walled carbon nanotubes grown by catalytic chemical vapor deposition were carboxylated in a two‐step oxidation process. An aqueous dispersion of the functionalized nanotubes was dispensed using an inkjet printer to obtain electrically conductive patterns on paper and plastic surfaces (see picture). Sheet resistivities for the deposited patterns of about 40 kΩ/□ could be achieved by multiple prints.
