The task of identifying the non-linearity of ferroelectric devices by using a ‘Quartic Double Well’ (QDW) model is addressed. A strategy for the estimation of model parameters fitting the dynamic behaviour of the device in a large range of frequencies is discussed. An experimental set-up for investigating the dynamic behaviour of a ferroelectric device is described and results are presented showing the capability of the proposed model to reproduce the hysteresis loops, at various frequencies and forcing field amplitudes.

Abstract
The task of identifying the non-linearity of ferroelectric devices by using a ‘Quartic Double Well’ (QDW) model is addressed. A strategy for the estimation of model parameters fitting the dynamic behaviour of the device in a large range of frequencies is discussed. An experimental set-up for investigating the dynamic behaviour of a ferroelectric device is described and results are presented showing the capability of the proposed model to reproduce the hysteresis loops, at various frequencies and forcing field amplitudes.File in questo prodotto:
