Carbon Nano Tubes- Ballistic Conductors

[taylaron]

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).

Perhaps someone could direct me to a research project that might know?

Thanks for trying!
