Carbon nanotubes may replace metals in electronic applications

چکیده
Telling about the yet another tantalizing property of CNTs that his research has revealed, Basarn says: 'It has been assumed that for carbon nanotubes, the electrical heating process would be governed by Joules law, where resistance in a circuit converts electric energy into heat. We are the first to show mathematically, from a quantum mechanics point of view, that carbon nanotubes do not follow Joules law.'

متن کاملEnergy gaps in "metallic" single-walled carbon nanotubes.
Metallic single-walled carbon nanotubes have been proposed to be good one-dimensional conductors. However, the finite curvature of the graphene sheet that forms the nanotubes and the broken symmetry due to the local environment may modify their electronic properties. We used low-temperature atomically resolved scanning tunneling microscopy to investigate zigzag and armchair nanotubes, both thou...
