Current response of ac-driven nanoelectromechanical systems in single-electron tunneling regime

preprint2010arXivOpen access

Abstract

We investigate electric current in a single-electron tunnelling device weakly coupled to an ac-driven underdamped harmonic nanomechanical oscillator. In the linear regime, the current can respond to the external frequency in a resonant as well as in an anti-resonant fashion. The main resonance is accompanied by an additional resonance at a half of the external frequency.
