Improved Hydrophobicity of Carbon Nanotube Arrays with Micropatterning

Langmuir, 2009
The hydrophobicity of vertically aligned multiwalled carbon nanotubes (MWCNTs) was improved through the creation of a parallel array of microwalls via a laser pruning technique. Changes to the hydrophobic nature of the patterned MWCNTs due to artificially induced roughness through variations in both the widths of the walls and the distance between ...

Large-Area Patterning of Carbon Nanotube Ring Arrays

Langmuir, 2009
Single-walled carbon nanotubes were assembled into large-area arrays of nanoscale rings on silicon via direct patterning with a self-assembled colloidal polystyrene sphere mask. Nanotubes from liquid suspension gathered at the base of each sphere in the mask to form rings, and the resulting arrays consisted of well-ordered nanotube rings with diameters

Potential Applications of Carbon Nanotube Arrays

2012
Aligned CNT assemblies have many applications besides what were discussed in the previous chapters. In this chapter, we introduce some potential applications of aligned CNTs, which is possible from theoretical point of view but might take a long time to realize because of the immature of the needed techniques.

Field Emission Characteristics of Regular Arrays of Carbon Nanotubes

Journal of Nanoscience and Nanotechnology, 2014
The developments of electronic devices based on micron-sized vacuum electron sources during the last decades have triggered intense research on highly efficient carbon based thin film electron emitters. The synthesis of massive arrays of carbon nanotubes that are oriented on patterned Fe catalyst deposited on quartz substrates is reported.

Self-similar organization of arrays of individual carbon nanotubes and carbon nanotube micropillars

Microelectronic Engineering, 2010
It is well-known that carbon nanotube (CNT) growth from a dense arrangement of catalyst nanoparticles creates a vertically aligned CNT forest. CNT forests offer attractive anisotropic mechanical, thermal, and electrical properties, and their anisotropic structure is enabled by the self-organization of a large number of CNTs. This process is governed by

Resonant properties of ordered carbon nanotube arrays

SPIE Proceedings, 2008
In this contribution we report mechanical resonance properties of ordered carbon nanotube arrays as elements of microwave and acoustic nanoelectromechanical systems in continuum approximation for frequency range 0.1 MHz - 70 GHz.

SIMULATION OF CARBON NANOTUBE THz ANTENNA ARRAYS

International Journal of Infrared and Millimeter Waves, 2006
A novel THz antenna structure, made of carbon nanotube arrays is suggested. Using CST MICROWAVE STUDIO (CST MWS), the capabilities of carbon nanotube terahertz (THz) antenna arrays have been simulated. The dependence of gain, upon geometrical factors, e.g., nanotube diameter, nanotube length and the inter-tubes distance, is shown.

Self-organized arrays of carbon nanotube ropes

Chemical Physics Letters, 2002
Abstract Aligned carbon nanotubes (CNTs) distributed uniformly on various substrates have been synthesized by chemical vapor deposition (CVD) method. Here, we report that by first depositing a film of amorphous carbon and random nanotubes, the aligned CNTs can self-organize into arrays of long macroscopic ropes on this film.

Electronic properties of armchair carbon nanotube array

Physica E: Low-dimensional Systems and Nanostructures, 2006
Abstract Magnetoelectronic properties of a 2D armchair carbon nanotube array are studied by the tight-binding model. The Lennard–Jones potential is used to determine the optimum geometry. Density of states (DOS), energy band, wave function, and energy gap strongly depend on the intertube interaction, the magnetic flux, and the Zeeman splitting.

Adsorption of Nitrogen in Carbon Nanotube Arrays

Langmuir, 1999
Grand canonical Monte Carlo molecular simulations have been carried out for adsorption of nitrogen at 77 K on square arrays of open and closed single-wall carbon nanotubes with diameters of 6−30 A and nanotube separations of 4−30 A. Exohedral spaces for arrays of closed nanotubes with small tube separations are microporous.
