How does that work? Wouldn't it be a low-efficiency one due to the higher material resistance?

Your info on CNTs are a few years out of date. There are some really remarkable experimental results that go beyond what the theory predicts.

  Thanks. I read up on it and found: The electrical resistance problem In October of last year an IBM-led team of researchers reported a solution to the electrical resistance problem. In a typical configuration metal contacts are attached to the top or the sides of the CNT. The team from IBM placed the contacts at the ends of the nanotube. They also joined the nanotube to the metallic components of the integrated circuit with a molybdenum-based carbide. Intel current top-of-the-line chips operate at a 14 nm scale and Intel plans to introduce 10 nm chips in 2017. The team from IBM built a CNT transistor that showed no increase in electrical resistance with contact lengths from 300 nm to less than 10 nm. https://www.forbes.com/sites/kevinmurnane/2016/09/08/carbon-nanotubes-are-getting-closer-to-making-our-electronic-devices-obsolete/#27ae198533d6 https://www.forbes.com/sites/kevinmurnane/2016/09/08/carbon-...
