Plasma-assembled carbon nanotubes: electric field-related effects.
This engineering-focused paper compares carbon nanotube growth in dense low-temperature plasma versus on a substrate surface using hybrid/Monte-Carlo simulations. It reports that plasma parameters strongly influence ion fluxes and nanotube growth kinetics, with large differences in growth rates and fluxes between plasma and surface growth. The authors suggest these dependencies may help select nanotube production methods.
Key points
- The study uses hybrid/Monte-Carlo numerical simulations to compare plasma-grown and surface-grown carbon nanotube processes.
- Plasma parameters are reported to significantly affect nanotube growth kinetics and ion fluxes.
- The abstract reports growth rate differences of up to three orders of magnitude between plasma and surface growth.
- Specific ion fluxes to nanotubes in plasma are reported to exceed those to surface-grown nanotubes by up to six orders of magnitude.
- The metal catalyst is described as experiencing very different conditions across production environments, potentially affecting growth mode.
- The reported relationships between plasma parameters, ion fluxes, and growth rates are presented as useful for choosing production methods.
