The present invention relates to a carbon nanotube structure and the preparation method thereof for easily controlling a Poisson's ratio. The carbon nanotube structure according to the present invention includes a plurality of carbon nanotubes that are tilted at a predetermined angle with respect to a direction of a first axis to which tension is applied and aligned. Here, a negative Poisson's ratio can be changed by controlling a tilt angle of the plurality of carbon nanotubes.

Detectors and methods of forming the same include aligning a semiconducting carbon nanotubes on a substrate in parallel to form a nanotube layer. The aligned semiconducting carbon nanotubes in the nanotube layer are cut to a uniform length corresponding to a detection frequency. Metal contacts are formed at opposite ends of the nanotube layer.

A method for processing carbon nanotubes includes positioning in a treatment chamber of a carbon nanotube processing apparatus a substrate having multiple carbon nanotubes bundled together and oriented substantially perpendicular to a surface of the substrate, and introducing a microwave into the treatment chamber from a planar antenna having multiple microwave radiation holes such that plasma of an etching gas is generated and that the plasma etches the carbon nanotubes starting from one end of the carbon nanotubes bundled together.

One or more techniques are disclosed for a method of functionalizing graphitic material, comprising the steps of: 1) providing a graphitic material; 2) cutting the graphitic material; 3) providing a catalyst comprising at least one catalyst of a metal atom, metal cation, metal alcoholates, metal alkanoates, metal sulfonates, and metal powder; 4) providing a reagent; 5) binding the catalyst to the reagent; 6) binding the reagent to the graphitic material; and 7) recovering the catalyst. Also disclosed is a composition prepared from the methods described herein.
