Temperature dependence of carbon nanofiber resistance.
نویسندگان
چکیده
Transport properties under current stress are examined for a carbon nanofiber (CNF) on an insulating substrate between tungsten-deposited gold electrodes. The temperature dependence of CNF resistance is determined based on our previously reported heat transport model. The measured devices exhibit a thermal activation behavior, suggesting transport in a disordered medium. The extracted activation energies fall within the 22-35 meV range.

Thermal Contact Resistance and Thermal Conductivity of a Carbon Nanofiber
We have measured the thermal resistance of a 152-nm-diameter carbon nanofiber before and after a platinum layer was deposited on the contacts between the nanofiber and the measurement device. The contact resistance was reduced by the platinum coating for about 9–13% of the total thermal resistance of the nanofiber sample before the platinum coating. At a temperature of 300 K, the axial thermal ...
متن کاملBranched carbon nanofiber network synthesis at room temperature using radio frequency supported microwave plasmas
Carbon nanofibers have been grown at room temperature using a combination of radio frequency and microwave assisted plasma-enhanced chemical vapor deposition. The nanofibers were grown, using Ni powder catalyst, onto substrates kept at room temperature by using a purposely designed water-cooled sample holder. Branched carbon nanofiber growth was obtained without using a template resulting in in...
متن کاملRelationship Between Strain and Electrical Resistivity of Vulcanized Rub- ber Filled with Carbon Nanofiber
Rubber material generally behaves as an electrical insulator, but vapor-grown carbon fiber (VGCF) is known for its electrical conductivity. Thus, we compounded styrene-butadiene rubber and carbon nanofiber (VGCF), and studied the relationship between strain and the DC electrical resistivity of vulcanized rubber filled with carbon nanofiber. No change of hardness was observed in hardness tests. ...
متن کاملPreparation and Photocatalytic Activity of TiO2-Wrapped Cotton Nanofiber Composite Catalysts
A novel TiO2-wrapped nanofiber composite catalyst, which possessed a unique porous structure and mixed crystalline phase, was prepared by the combination of superficial sol–gel and post-calcination processes. By means of the superficial sol–gel process, TiO2 layers were deposited on the surface of each nanofiber-like cellulose fiber, and then the TiO2wrapped nanofiber composite catalysts were c...
متن کاملRemoval of Formaldehyde with Activated Carbon Nanofiber Delivered from Electrospun Pan-cf
The adsorption behavior of formaldehyde has been examined using PAN based activated carbon nanofibers (PACNF). PACNF was prepared through the processes of oxidation stabilization and successive steam activation of electrospun polyacrylonitrile nanofiber (Diameter: avg.800nm, Nanotechnics, South Korea). Among simple heat treated PAN nanofibers in the temperature range of 500~800C, PAN carbon nan...
