Isn't it a problem that carbon is mostly one of the things you make nearly every resistor out of, instead of wires?

- chaxor 3y agoArmchair swcnts are ballistic conductors. It matters quite a lot how that carbon is oriented.
- Gordonjcp 3y agoHow well do they conduct? At the moment aluminium is kind of the "sweet spot" between weight, cost, and conductivity.
- chaxor 3y agoBallistic conduction means 'perfect' conduction in a sense. There's no resistance. It's only for armchair swcnts though. Other metallic swcnts are also great conductors, but if you separate out the chiralities (semiconductors, etc) you might as well separate to just armchairs.
