Carbon Nanotube Arrays Prepared by MWCVD
The Journal of Physical Chemistry B, 2001Highly aligned carbon nanotubes (NTs) have been directly grown on metallic surfaces and in the channels of anodic aluminum oxide (AAO) templates at a low temperature by bias-enhanced microwave plas...

Precise pitch-scaling of carbon nanotube arrays within three-dimensional DNA nanotrenches
Science, 2020DNA bricks build nanotube transistors Semiconducting carbon nanotubes (CNTs) are an attractive platform for field-effect transistors (FETs) because they potentially can outperform silicon as dimensions shrink. Challenges to achieving superior performance

Electromagnetic vortices in an array of carbon nanotubes [PDF]
Bulletin of the Russian Academy of Sciences: Physics, 2012 The dynamics of electromagnetic vortices in an array of carbon nanotubes is investigated. The electromagnetic field is described by Maxwell (two-dimensional wave) equations. Calculation modeling is performed. The resulting mass center velocity of the vortices is zero, and the intensity distribution its field changes periodically over time.

Abstract A simple acid treatment method was applied to remove the catalyst impurities and other residues contaminated in the vertically aligned carbon nanotube arrays. We demonstrated that acid treatment was an efficient approach for aligned carbon nanotube purification.

Improved Hydrophobicity of Carbon Nanotube Arrays with Micropatterning
Langmuir, 2009The 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 ...

Carbon nanotube arrays for photovoltaic applications
JOM, 2007Vertically aligned periodic arrays of carbon nanotubes (CNTs) are used to create topographically enhanced light-trapping photovoltaic cells. The CNTs form the back contact of the device and serve as a scaffold to support the photoactive heterojunction.

Highly pure semiconducting single-walled carbon nanotubes (SWNTs), sorted by density-gradient ultracentrifugation, undergo self-assembly using depletion attraction forces into rafts along lithographically defined patterns of narrow pitch (100 or 200 nm).

Scattering Properties of Carbon Nanotube Arrays
IEEE Transactions on Electromagnetic Compatibility, 2012Interaction of carbon nanotubes (CNTs) with electromagnetic waves has not been extensively investigated, nor is well understood. In this paper, we examine the scattering behavior of finite CNTs arrays at terahertz frequencies. To this end, we employ a method of moment (MoM) analysis in conjunction with the thin wire approximation capable of analyzing ...

Carbon nanotube array smart materials
SPIE Proceedings, 2006Highly aligned multi-wall carbon nanotube arrays up to 4 mm tall were synthesized on Si wafers using a chemical vapor deposition process with water delivery. Based on the long nanotube arrays, several prototype smart materials were developed including a biosensor, electrochemical actuator, and nanotube probes.

Carbon Nanotube Array for Infrared Detection [PDF]
, 2008 Abstract : The core effort of this project has been the electrical transport and infrared photoresponse properties of carbon nanotube (CNT) systems. The word system is important in the context of our work because we have focused on the properties of materials and devices consisting not of a single CNT, but of assemblies with large numbers of CNTs.
