Electrochemical oxidation of single wall carbon nanotube bundles in sulfuric acid
Article Abstract:
Electrochemical doping of bisulfate ions into single wall carbon nanotube (SWNT) bundles was investigated through coulometry, cyclic voltammetry, mass-uptake measurements and Raman scattering experiments. A spontaneous charge-transfer reaction was seen prior to the use of an electrochemical driving force which is very different to previous findings in the graphite-H2SO4 system. A mass increase of the SWNT sample and a concomitant upshift of the Raman-active tangential mode frequency indicated oxidation of the SWNT bundles.

Synthesis and characterization of amorphous carbon nanotubes by pyrolysis of ferrocene confined within AAM templates
Article Abstract:
A template method for the synthesis of amorphous carbon nanotubes (a-CNTs), in combination with the closed space sublimation(CSS) technique, which were used to prepare single crystalline semiconductor nanowires are presented. Electrical transport measurement on individual a-CNTs demonstrate that the a-CNT might be connected with electrodes via either ohmic or Schottky contacts.
