Electromechanics also operates at the nanoscale

What limits the behaviour of a carbon nanotube? This is a question that many scientists are trying to answer. Physicists at University of Gothenburg, Sweden, have now shown that electromechanical principles are valid also at the nanometre scale. In this way, the unique properties of carbon nanotubes can be combined with classical physics - and this may prove useful in the quantum computers of the future.
