    摘要: Nanosized filamentary carbon structures (CNTs) nucleating over a catalyzed surface may be grown in an up-right direction reaching a second surface, spaced from the first surface, without the need of applying any external voltage source bias. The growth process may be inherently self-stopping, upon reaching a significant population of grown CNTs on the second surface. A gap between the two surfaces may be defined for CNT devices being simultaneously fabricated by common integrated circuit integration techniques. The process includes finding that for separation gaps of up to a hundred or more nanometers, a difference between the respective work functions of the materials delimiting the gap space, for example, different metallic materials or a doped semiconductor of different dopant concentration or type, may produce an electric field intensity orienting the growth of nucleated CNTs from the surface of one of the materials toward the surface of the other material.

    摘要: Described herein is an optically controlled electrical-switch device which includes a first current-conduction terminal and a second current-conduction terminal, and a carbon nanotube connected between the first and the second current-conduction terminals, the carbon nanotube being designed to be impinged upon by electromagnetic radiation and having an electrical conductivity that can be varied by varying the polarization of the electromagnetic radiation incident thereon. In particular, the carbon nanotube may for example, in given conditions of electrical biasing, present a high electrical conductivity when it is impinged upon by electromagnetic radiation having a given wavelength and a polarization substantially parallel to the axis of the carbon nanotube itself, and a reduced electrical conductivity when it is impinged upon by electromagnetic radiation having a given wavelength and a polarization substantially orthogonal to the axis of the carbon nanotube itself.

    摘要: 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.
