摘要
We investigate the dynamics of electrically ac-driven nanoelectromechanical shuttle arrays. The electromechanical coupling enforces long-range interactions. We find multistability regimes upon changing the voltage and frequency. We show that the instability driven by parametric amplification of sinusoidal mechanical waves leads to the creation of spatially localized mechanical oscillations, discrete breathers, and subsequently to an abrupt change in the electrical transport properties. In particular, we find current rectification, which is induced by the excitation of discrete breathers. This is of potential interest and use for nanomechanical sensor application.
