Abstract
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.
