Dynamic characterisation and model identification in ferroelectric thin films
نویسندگان
چکیده
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.

Tunable Schottky Barrier in Photovoltaic BiFeO3 Based Ferroelectric Composite Thin Films
We examine the photo-assisted polarization loop in a BiFeO3 thin film under UV light illumination. BiFeO3 thin film prepared by pulsed laser deposition method onto the BaTiO3 thin film and the polarization behavior has been measured under poling voltage. Our results show the engineered polarization due to controllable schottky barrier under inverse poling voltage. This control on schottky barri...
متن کاملA possible mechanism of anomalous shift and asymmetric hysteresis behavior of ferroelectric thin films
We studied theoretically the hysteresis behavior of ferroelectric thin films. The anomalous ferroelectric response is discussed by use of a bilayer model. Electrical conductivities of the films have been taken into account. To model the effects of the inhomogeneity of polarization and permittivity across the interface, the film is assumed to possess a secondary dielectric/ferroelectric phase sa...

The effects of non-equally biaxial in-plane misfit strains on the equilibrium polarization states and the dielectric properties of single-domain epitaxial ferroelectric thin films are investigated by a nonlinear thermodynamic theory. The “misfit strain-misfit strain” and “temperature-misfit strain” phase diagrams for single-domain BaTiO3 (BT) and PbTiO3 (PT) thin films grown on tetragonal subst...

متن کاملDielectric properties of ferroelectric thin films with surface transition layers.
By taking into account surface transition layers (STL), the dielectric properties of ferroelectric thin films described by the transverse Ising model are discussed in the framework of the mean field approximation. Functions of the intra-layer and inter-layer couplings are introduced to characterize STL, which makes the model more realistic compared to previous treatment of surface layers using ...
