Carbon Nanotubes Electronics exhibit remarkable electrical and mechanical properties. In particular, they behave as one-dimensional conductors, which can either be metallic or semiconducting. Metallic SWNTs have extremely low resistivity, and a single tube can sustain a current of tens of microamps. SWNTs have also demonstrated significant promise as atomic force microscopy (AFM) tips. “Tube tips” offer important advantages over conventional silicon microfabricated probes, including increased lateral resolution due to the Msmall tube diameter (1-2 nm), a high aspect ratio, and damage resistance resulting from reversible elastic buckling.

Carbon Nanotubes Electronics have many potential applications in electronics and photonics. Photoconductive detection is apparently very weak, but have reported a sensitive bolometric Near Infrared detector based on a Carbon Nanotube (CNT) film. Microwave detection using semi-conducting SWNT (s-SWNT) Schottky barriers, s-SWNTs, and CNT-FETs has been extended to 110 GHz.

Carbon Nanotubes Electronics exhibit remarkable electrical and mechanical properties. In particular, they behave as one-dimensional (1D) conductors, which can either be metallic or semiconducting. Metallic SWNTs have extremely low resistivity, and a single tube can sustain a current of tens of microamps. “Tube tips” offer important advantages over conventional silicon microfabricated probes, including increased lateral resolution due to the small tube diameter (1-2 nm), a high aspect ratio, and damage resistance resulting from reversible elastic buckling. Also, through selective chemical modification of the free end of the nanotube, tube tips can be employed to probe the functionality of surface chemical groups and biological molecules.

Thin-film solar cell structure in whichthe traditional transparent conductive oxide electrode(ZnO) is replaced by a transparent conductive coating consisting of a network of bundled Carbon Nanotubes Electronics. Optical transmission properties of these coatings are presented in relation to their electrical properties (sheet resistance), along with preliminary solar cell results from devices made using CuIn1-xGaxSe2 thinfilm absorber materials. Achieving an energy conversion efficiency of >12% and a quantum efficiency of ~80% demonstrate the feasibility of the consent.
