A RIGOROUS COMPARISON OF METHODS FOR MULTI-WALLED CARBON NANOTUBES PURIFICATION USING RAMAN SPECTROSCOPY
Multi-walled carbon nanotubes (MWNT’s) were synthesized using chemical vapor deposition (CVD) method in a fluidized bed reactor under the flow of methane and hydrogen gases. A Cobalt-molybdenum/magnesium oxide (Co-Mo/MgO) nanocatalyst was used as the catalyst of the process. The samples were analyzed using scanning electron microscopy (SEM) and X-ray diffraction (XRD) analyses. The effects of d...
متن کاملElectrical and Raman spectroscopic studies of vertically aligned multi-walled carbon nanotubes.
Microwave plasma enhanced chemical vapour deposition (MPECVD) was used for the production of carbon nanotubes. Vertically aligned multi-walled carbon nanotubes (MWCNTs) were grown on silicon substrates coated with cobalt thin films of thickness ranging from 0.5 nm to 3 nm. Prior to the nanotube growth the catalyst were treated with N2 plasma for 5-10 minutes that break the films into small nano...
متن کاملElectron Transport in Single-Walled Carbon Nanotubes
Electron Transport in Single-Walled Carbon Nanotubes Meninder S. Purewal We present electron transport experiments on single walled carbon nanotubes (SWNTs). By measuring the linear scaling of resistance with length, we determine an unusually long mean free path of Lm ∼1 μm at room temperature. From the temperature dependence of the mean free path for over 10 samples we show that inelastic scat...
متن کاملTransport Spectroscopy of Single-Walled Carbon Nanotubes
We have performed transport spectroscopy on individual ropes of single-walled carbon nanotubes. We find that the levels are Zeeman split in a magnetic field, with a g-factor of 2.04 ± 0.05. The observed pattern of peak splittings indicates the parit y of the number of electrons on the dot. In one device there are also signs of the presence of a second dot. We observe features which resemble ant...
