Strong feedback and current noise in nanoelectromechanical systems
Strong feedback and current noise in nanoelectromechanical systems
We demonstrate the feasibility of a strong feedback regime for a single-electron tunneling device weakly coupled to an underdamped single-mode oscillator. In this regime, mechanical oscillations are generated and the current is strongly modified, whereas the current noise is parametrically large with respect to the Poisson value. This regime requires …
