One-way rotation of a molecule-rotor driven by a shot noise. Echeverria, J., Monturet, S., & Joachim, C. Nanoscale, 6(5):2793–2799, February, 2014. Publisher: The Royal Society of Chemistry
Paper doi abstract bibtex The shot noise of a tunneling current passing through a molecule-motor can sustain a one-way rotation when populating the molecular excited states by tunneling inelastic excitations. We demonstrate that a ratchet-like ground state rotation potential energy curve is not necessary for the rotation to occur. A relative shift in energy difference between the maxima of this ground state and the minima of the excited states is the necessary condition to get to a unidirectional rotation. The rotor speed of rotation and its rotation direction are both controlled by this shift, indicating the necessity of a careful design of both the ground and excited states of the next generation of molecule-motors to be able to generate a motive power at the nanoscale.
