A carbon nanotube composite structure includes a carbon nanotube and a film-like structure. The carbon nanotube includes a p-type portion and an n-type portion. The film-like structure is a molybdenum disulfide film or a tungsten disulfide film, and the film-like structure covers the n-type portion.

The present invention provides a laminate structure in which the properties of a single-walled CNT, which are susceptible to surrounding environment, are stabilized by protecting the surface of the single-walled CNT with a proper substance, and/or another property is imparted to the single-walled CNT. The present invention provides a structure which comprises a first single-walled carbon nanotube having a length of 50 nm or longer, preferably 100 nm or longer, and a second layer laminated on the first single-walled carbon nanotube, wherein the second layer comprises at least one substance selected from the group A consisting of first boron nitride, first transition metal dichalcogenide, second carbon, first black phosphorus and first silicon.

A method for arranging nanotube elements within nanotube fabric layers and films is disclosed. A directional force is applied over a nanotube fabric layer to render the fabric layer into an ordered network of nanotube elements. That is, a network of nanotube elements drawn together along their sidewalls and substantially oriented in a uniform direction. In some embodiments this directional force is applied by rolling a cylindrical element over the fabric layer. In other embodiments this directional force is applied by passing a rubbing material over the surface of a nanotube fabric layer. In other embodiments this directional force is applied by running a polishing material over the nanotube fabric layer for a predetermined time. Exemplary rolling, rubbing, and polishing apparatuses are also disclosed.

A connection structure of a carbon nanotube wire is provided, which includes a joint between the carbon nanotube wire and the connection target having excellent electrical connectivity and mechanical connectivity. The present disclosure provides a connection structure of a carbon nanotube wire, including: a carbon nanotube wire formed by twisting and bundling carbon nanotube aggregates; a connection target to which the carbon nanotube wire is connected; a conducting wire with higher solder wettability than the carbon nanotube wire; a penetrating part of the conducting wire formed along a cross section having a component orthogonal to a longitudinal direction of the carbon nanotube wire; and solder that connects the carbon nanotube wire and the connection target, in which the solder penetrates the penetrating part formed along the conducting wire.

A process for making a carbon nanotube structure includes forming a composite by depositing or growing carbon nanotubes onto a metal substrate, and infusing the carbon nanotubes. In other aspects, a method of making a wire, includes coating carbon nanotubes on a wire, and electroplating the carbon nanotubes. In still other aspects, a method of making a conductor includes growing or depositing vertically aligned carbon nanotubes on a sheet. Yet still, a method of making a cable includes forming multiple composite wires, each composite wire formed by depositing or growing carbon nanotubes onto a metal substrate, and performing a metal infusion of the carbon nanotubes. The method also comprises combining multiple finished composite wires or objects to make large cables or straps.
