Carbon Nano Tubes- Ballistic Conductors

Click For Summary
SUMMARY

The discussion centers on the electrical resistance of single-walled carbon nanotubes (SWCNTs) when stacked to form a line. Tay inquires whether the overlapping of approximately 50nm long metallic SWCNTs introduces resistance, despite their classification as ballistic conductors, which typically exhibit no resistance. The key point raised is the potential for increased resistance at the contact points between the nanotubes due to reduced surface area, contrasting with the ideal performance of a single, continuous ballistic conductor.

PREREQUISITES
  • Understanding of single-walled carbon nanotubes (SWCNTs)
  • Knowledge of ballistic conduction principles
  • Familiarity with electrical resistance concepts
  • Basic grasp of nanotechnology manufacturing methods
NEXT STEPS
  • Research the electrical properties of single-walled carbon nanotubes (SWCNTs)
  • Explore the concept of ballistic conduction in nanomaterials
  • Investigate methods for measuring resistance in nanoscale materials
  • Look into current advancements in carbon nanotube manufacturing techniques
USEFUL FOR

Researchers, materials scientists, and electrical engineers interested in nanotechnology, specifically those studying the electrical properties and applications of carbon nanotubes.

Hey guys, I'm researching single walled carbon nanotubes and I am trying to find out how much approx. Resistance there is in a pile of ~50nm long metallic SWCNT's piled on top of each other to form a line (think laying gunpowder for a fuse...). I'm perplexed because SWCNT's at the proper size are ballistic conductors (no resistance). This poses an interesting situation because I would suspect traveling from one CNT to another identical one via the point where they touch would create resistance because of the reduced surface area.

So the question is: does a series of metallic SWCNT's overlapping each other to form a line create resistance opposed to a single CNT that is a ballistic conductor which is also the same length of the line (which is generally impossible with todays manufacturing methods given a reasonable distance of a few millimeters).

Regards,
