Aligned, high-density semiconducting carbon nanotube arrays for high-performance electronics

Science, 2020
Aligning dense carbon nanotube arrays Although semiconducting carbon nanotubes (CNTs) are promising candidates to replace silicon in transistors at extremely small dimensions, their purity, density, and alignment must be improved. Liu et al.

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 ...

The growth of freestanding single carbon nanotube arrays [PDF]

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

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.

Flexible carbon nanotubes photosensor array

2010 IEEE 23rd International Conference on Micro Electro Mechanical Systems (MEMS), 2010
This study reports a flexible CNTs (carbon nanotubes) photosensor array for light detection. In this device, the CNTs for light detection are embedded into the flexible Parylene-C film. The batch fabricated flexible CNTs photosensor array using the micromachining processes is implemented.

Carbon Nanotube Micro-Electrode Array

TRANSDUCERS 2007 - 2007 International Solid-State Sensors, Actuators and Microsystems Conference, 2007
A novel class of micro electrodes, specifically designed to interface with neuronal systems, is presented. The electrodes were fabricated by synthesizing high density carbon nanotube islands on lithographically defined, passivated titanium nitride conductors on a silicon dioxide substrate.

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.

Neural Stimulation with a Carbon Nanotube Microelectrode Array

Nano Letters, 2006
We present a novel prototype neural interface using vertically aligned multiwalled carbon nanotube (CNT) pillars as microelectrodes. Functionalized hydrophilic CNT microelectrodes offer a high charge injection limit (1-1.6 mC/cm2) without faradic reactions.

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.

Aligning dense carbon nanotube arrays

Science, 2020
Device Technology Although semiconducting carbon nanotubes (CNTs) are promising candidates to replace silicon in transistors at extremely small dimensions, their purity, density, and alignment must be improved. Liu et al. combined a multiple dispersion sorting process, which improves purity, and a dimension-limited self-alignment process to produce ...
