Nanoelectromechanics of shuttle devices
Journal article, 2013
A single-electron tunneling (SET) device with a nanoscale
central island that can move with respect to the bulk sourceand
drain electrodes allows for a nanoelectromechanical
(NEM) coupling between the electrical current through the device
and the mechanical vibrations of the island. Although
the electromechanical “shuttle” instability and the associated
phenomenon of single-electron shuttling were predicted more
than 15 years ago, both theoretical and experimental studies
of NEM-SET structures are still carried out. New functionalities
based on quantum coherence, Coulomb correlations and
coherent electron-spin dynamics are still of particular interest.
In this article we present a short review of recent activities in this area.
