According to some embodiments, the present invention provides a system and method for supporting a carbon nanotube array that involve an entangled carbon nanotube mat integral with the array, where the mat is embedded in an embedding material. The embedding material may be depositable on a carbon nanotube. A depositable material may be metallic or nonmetallic. The embedding material may be an adhesive material. The adhesive material may optionally be mixed with a metal powder. The embedding material may be supported by a substrate or self-supportive. The embedding material may be conductive or nonconductive. The system and method provide superior mechanical and, when applicable, electrical, contact between the carbon nanotubes in the array and the embedding material. The optional use of a conductive material for the embedding material provides a mechanism useful for integration of carbon nanotube arrays into electronic devices.

Embedded arrays of vertically aligned carbon nanotube carpets and methods for making them

A method for forming nanotube electrical devices, arrays of nanotube electrical devices, and device structures and arrays of device structures formed by the methods. Various methods of the present invention allow creation of semiconducting and/or conducting devices from readily grown SWNT carpets rather than requiring the preparation of a patterned growth channel and takes advantage of the self-controlling nature of these carpet heights to ensure a known and controlled channel length for reliable electronic properties as compared to the prior methods.

Electrical device fabrication from nanotube formations

A new and useful nanotube growth substrate conditioning processes is herein disclosed that allows the growth of vertical arrays of carbon nanotubes where the average diameter of the nanotubes can be selected and/or controlled as compared to the prior art.

Carbon nanotube diameter selection by pretreatment of metal catalysts on surfaces

A method is disclosed for producing graphenic materials by templated growth along a preformed graphenic material lattice edge, wherein at least one of the graphenic material or template is translated during growth of the graphenic material. A method for preparing CNTs from preformed CNT substrates in the presence of cylindrical templating structures and a reactive carbon source in a fluid phase is also disclosed, wherein at least one of the CNT substrate or the cylindrical templating structure is translated during addition of carbon atoms to the CNT substrate. A method is also disclosed for preparing CNTs from preformed CNT substrates in the presence of cylindrical templating structures and a carbon source in a fluid phase, wherein non-thermalized excited states are produced on the CNT substrate and at least one of the CNT substrate or the cylindrical templating structure is translated during addition of carbon atoms to the CNT substrate.
