Summary :

The model to calculate high frequency C-V characteristics of ferroelectric capacitors that have not been modeled yet is presented. At first, P-V hysteresis model necessary to calculate C-V characteristics is improved by introducing two modification factors and by comparing with experimental results. Then, other parameters to express high frequency C-V characteristic of the metal/ferroelectric/metal structure are derived, in which the response for AC signal input is considered. Finally, it has been shown that these models predict well the C-V hysteresis shapes of the MFIS and the MFMIS structures.
