Abstract

We show that there is a regime of strong feedback for a nanomechanical oscillatory mode weakly coupled to a single-electron tunneling device. In this regime, the current is strongly modified whereas the current noise is parametrically big exceeding the Schottky limit by orders of magnitude. This regime requires a high quality factor of nanomechanical oscillations.
