ABSTRACT
A theoretical model is presented to numerically examine the effects of doping concentration and thickness on potential and electric field distributions in ferroelectric thin films. The numerical results indicate that the film depletion is affected significantly by the thickness and the space charge concentration. It is found that the increase in the space charge density would strengthen the electric field in the vicinity of the electrode interface. We also found that the dielectric constant is enhanced and the film polarization is weakened remarkably with increasing the space charge density for a given film thickness.
