Carbon nanotube array smart materials

SPIE Proceedings, 2006
Highly 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.

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

Chemically assisted directed assembly of carbon nanotubes for the fabrication of large-scale device arrays.

Journal of the American Chemical Society, 2007
We report the directed assembly of single-walled carbon nanotubes (SWCNTs) at lithographically defined positions on gate oxide surfaces, allowing for the high yield ( approximately 90%) and parallel fabrication of SWCNT device arrays.

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 ...

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.

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.
