                     One-dimensional nanomaterials DWCNTs,semiconductor film used doble walled carbon nanotubes

 

Spec: 2-5nm , 1-2um or 5-20um length, >91% purity.


Double-walled carbon nanotubes are considered to be the final one-dimensional line on the basis of pure carbon. Double-walled carbon nanotube defect-free with a smooth surface with atomic precision on the nanometer manufacturing a bearing hope. DWNTs open at both ends, between the inner and outer layers of vibration in the axial direction can to GHZ level, is a good material for the preparation of nano-oscillator.

 

Double-walled carbon nanotubes are one-dimensional material between the important single-walled and multi-walled carbon nanotubes between the inner and outer layers of its chiral parameters and the inner and outer tube spacing relevant, between 0.33 nm and 0.42 nm, than Common-layer multi-walled carbon nanotubes spacing. Because of the double-walled carbon nanotubes between the inner and outer layers of weak interactions tube, which led to a double-walled carbon nanotubes have unique band structure, it can be expected to have unique electrical and optical properties.

 

Double-walled carbon nanotubes and single-walled carbon nanotube electrical properties similar performance as conductor at room temperature, while different from the multi-walled carbon nanotubes. With increasing temperature, double-walled carbon nanotube resistivity was reduced after the first rising trend, there is a minimum point resistivity. Double-walled carbon nanotube film from the semiconductor body transformation guide Tk characteristic temperature can reach 32 K, than a single single-walled carbon nanotube bundles 35 K lower.
