| Abstract: | The dependence of switching currents and switching time of a circular ferroelectric thin film and a ferroelectric sphere on thier sizes is investigated based on the Orihara|Ishibashi theory for ferroelectric domain reversals.Computational results indicate that,for both systems,the switching current drops with decreasing system size and the switching time shortens as the system size decreases. |

| Keywords: | ferroelectric ferroelectric domain switching characteristic size. |
