Scattering properties of carbon nanotube arrays

International Journal of Microwave and Wireless Technologies, 2010
In this paper, we investigate the scattering properties of an array of finite-length single-walled carbon nanotubes (SWCNTs), up to terahertz frequencies. The problem is cast in terms of a Pocklington-like equation. The current density along the CNT is described by a quasi-classical transport model, recently proposed. The numerical solution is obtained

Ice-Assisted Transfer of Carbon Nanotube Arrays

Nano Letters, 2015
Decoupling the growth and the application of nanomaterials by transfer is an important issue in nanotechnology. Here, we developed an efficient transfer technique for carbon nanotube (CNT) arrays by using ice as a binder to temporarily bond the CNT array and the target substrate.

Scattering Properties of Carbon Nanotube Arrays

IEEE Transactions on Electromagnetic Compatibility, 2012
Interaction 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 ...

Electrostatic analysis of carbon nanotube arrays

International Conference on Simulation of Semiconductor Processes and Devices, 2003. SISPAD 2003., 2003
In order to improve the performance of carbon nanotube field effect transistors (CNFETs), a nanotube array should be used. For a densely packed array of nanotubes, screening by nearby tubes affects the capacitance per tube. The gate-to-channel capacitance for a nanotube array of three different gate electrode configurations was examined in this study ...

Simulation of carbon nanotube photovoltaic arrays

SPIE Proceedings, 2010
Exploring renewable, sustainable and green energy resources is a critical challenge for scientists and engineers. Large-scale ambient energy, such as the solar energy is available but current technologies are not yet ready to capture it with great efficiency.

Transmission and scattering properties of carbon nanotube arrays

2009 International Symposium on Electromagnetic Compatibility - EMC Europe, 2009
This paper investigates the behavior of an array of parallel Carbon Nano Tubes (CNTs), when it is illuminated by a plane wave. Transmission and scattering properties are quantified. This analysis may be used in the future as a reference for shielding applications based on CNT arrays.

The growth of freestanding single carbon nanotube arrays

Nanotechnology, 2003
Regular arrays of freestanding single carbon nanotubes (CNTs) were prepared on Ni dot arrays by dc plasma-enhanced chemical vapour deposition. The size of the Ni dot was reduced for single CNT growth by means of conventional photolithography and a lateral wet-etch process. The vertical alignment of a single CNT was directly dependent on the location of

Electrochemical Modification of Vertically Aligned Carbon Nanotube Arrays

The Journal of Physical Chemistry B, 2006
Electrochemical oxidation and reduction were utilized to modify vertically aligned carbon nanotube (CNT) arrays grown on a porous network of conductive carbon microfibers. Ultrafast and complete CNT opening and purification were achieved through electrochemical oxidation. Highly dispersed platinum nanoparticles were then uniformly and densely deposited

Quasi-Continuous Growth of Ultralong Carbon Nanotube Arrays

Journal of the American Chemical Society, 2005
We report the growth of ultralong (>10 cm) multi-walled and single-walled carbon nanotubes such that the length is limited by the size of the furnace rather than by the termination of growth. The disturbance of microscale laminar flows results in disordered or shorter growth of carbon nanotubes.

Preparation of Horizontal Single-Walled Carbon Nanotubes Arrays

Topics in Current Chemistry, 2016
The synthesis of SWNTs has achieved great success with the development of synthetic methodologies. From the viewpoint of exploiting the exceptional electrical properties of single-walled carbon nanotubes (SWNTs) in advanced applications, one of the most difficult challenges is how to assemble the SWNTs with high degrees of alignment and purity in ...
