摘要：

A harmonic nanomechanical oscillator with a high quality factor weakly coupled to a single-electron tunneling device can provide a strong feedback for electron transport. Strong feedback occurs in a narrow voltage range just above the Coulomb blockade threshold. In this regime, current is strongly modified and current noise is drastically enhanced compared to the Schottky value.
