Nanoshel’s Single Walled Nano Tube can be conducting or semi-conducting types depending on the type of chirality Semiconducting SWNTs are usually in the form of p-type semiconductors. MWCNTs are composed of many tubes of SWCNTs and therefore are not likely to be strictly one-dimensional conductors. A pseudo-gap was observed in measurements, which attributes to its conducting natureThe important aspect of CNT emitters is that the emission can be obtained at a lower threshold voltage. Semiconductor Single Walled Nano Tube can also be used in sensors, micron-scale on-chip triodes at a high frequency (>200 MHz), vacuum microelectronics, and for X-ray generation.

Nanoshel’s Semiconductor Single Walled Nano Tube exhibit remarkable electrical and mechanical properties. In particular, they behave as one-dimensional (1D) conductors, which can either be metallic or semiconducting. Semiconductor Single Walled Nano Tube 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.

Nanoshel’s Single Walled Nano Tube 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.

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.

Nanoshel’s Single Walled Nano Tube can be doped either by electron donors or electron acceptors. After reaction with host materials, the dopants are intercalated in the intershell spaces of the multiwalled nanotubes, and in the case of single-walled nanotubes either in between the individual tubes or inside the tubes. The reaction of intercalation can be carried out in the vapour or liquid phase, and electrochemically.
This material ships as dry granules or powder. Each grade contains particles with an average thickness and surface area. All dimensions represent median sizes and there is a distribution around the mean. Nanoshel offers Semiconductor Single Walled Nano Tubes to Nanoparticles with wide variety of application and offers full scale projects for researchers. by Nanoshel.
