摘要

This paper studies the nonlinear vibration of a ZnO nanowire driven by an external electric field. The equation of motion for the nanowire with a nonlinear elastic deformation is formulated. The numerical computation results reveal the nonlinear vibration behaviors of the nanowire subject to the applied electric field with the piezoelectric field effect. The results agree with the experimental observations in the nanowire deflection behaviors. It is demonstrated that the nanowire is in a finite periodic oscillation subject to the applied field strength, with bifurcations leading to resonance recurrence.
