摘要
Simulations of ferroelectric characteristics have been carried out using a one-dimensional model of polarization reversal in ferroelectrics in which latent nuclei are randomly distributed. Characteristics studied include pulse response, P-e hysteresis loops, differential electric susceptibility versus applied field (dP/de-e curves) and switching current versus applied field (i-e curves) in ferroelectrics. Results of simulations show that P-e hysteresis loops, dP/de-e curves and i-e curves depend on the viscosity which causes the delay in motion of the individual dipole moment, the interaction between neighboring atoms and the applied field.
