Description:
Author(s): T. Barois, S. Perisanu, P. Poncharal, P. Vincent, S. T. Purcell, and A. Ayari Nanoelectromechanical oscillators are conventionally operated near their resonant frequency, where they are ultrasensitive to tiny signals. The authors show that, counterintuitively, a SiC nanowire resonator coupled to an overdamped electrical circuit, and driven above both resonance and cutoff frequencies, gives b e t t e r performance than one with conventional tuning, and can self-oscillate. This method is simple and can be generalized to any electromechanical system, for e . g . force sensing, or studying synchronization phenomena. [Phys. Rev.
