In the case of asymmetric setup, the system behaves as a rectifier. For pure ac drive, the rectified current shows a rather rich frequency dependent response characterized by frequency locking at fractional values of the external frequency. Because of the nonlinear dynamics of the shuttle, rectification is present also for very low frequencies. These effects could be useful to unveil the internal dynamics of nanomechanical devices. © 2005 The American Physical Society. 关键词: Electric rectifiers;Electric charge;Semiconductor junctions;Oscillations;Energy dissipation;Electron tunneling;Damping;Transistors;Electrodes;Nonmechanical rectifiers;Oscillating molecules;Quantum transport;Frequency locking
