摘要
We investigate the dynamic characteristics of electric polarization P(t)in a ferroelectric junction under ac applied voltage and stress,and calculate the frequency response and the cut-off frequency f0,which provides a reference for the upper limit of the working frequency.Our study might be significant for sensor and memory applications of nanodevices based on ferroelectric junctions.
