A method for growing carbon nanotubes having a determined chirality includes fragmenting at least one initial carbon nanotube having a determined chirality to obtain at least two portions of carbon nanotube. Each portion has a free growth end. Atoms of carbon are supplied with an autocatalyst addition of the atoms of carbon at the free growth end of each portion of nanotube to determine an elongation or growth of the nanotube.

The present invention relates to a new light emitters that exploit the use of semiconducting single walled carbon nanotubes (SWNTs). Experimental evidences are given on how it is possible, within the standard silicon technology, to devise light emitting diodes (LEDs) emitting in the infrared IR where light emission results from a radiative recombination of electron and holes on semiconducting single walled carbon nanotubes (SWNTs-LED). We will also show how it is possible to implement these SWNTs-LED in order to build up a laser source based on the emission properties of SWNTs. A description of the manufacturing process of such devices is also given.

Described herein are a molecular memory obtained using DNA strand molecular switches and carbon nanotubes, and a manufacturing method thereof. In particular, the nonvolatile memory is manufactured according to an architecture that envisages the use of carbon nanotubes as electrical connectors and DNA strands as physical means on which to write the information. In other words, the nonvolatile memory is made by means of a set of molecular DNA strand switches, the addressing of which is controlled by molecular wires made up of carbon nanotubes.
