Abstract
A harmonic shear end force induced the transient bending vibration is analyzed in a cantilevered n-type ZnO nanofiber. Based on the mechanical movement equation, continuity condition of current density and charge equation of electrostatics, the theoretical analysis is carried out by a one-dimensional model. The evolution of the deflection and perturbation of the electron concentration caused by the harmonic end force are calculated. Numerical results show that the vibration period of the piezoelectric semiconductor fiber is about twice that of the harmonic force, which referenced to design the nanosensors and nanogenerators.
