Surface state on first-order ferroelectrics
(Springer Berlin / Heidelberg, 2006)
In the presence of a surface the Landau-Devonshire equations of ferroelectricity must be extended to include a boundary condition. For a ferroelectric with a second-order transition in the case when the polarization p(z) ...
A numerical approach of Polarization profile for First-Order Ferroelectric film system using Finite-Difference method
(Kolej Universiti Kejuruteraan Utara Malaysia, 2005-05-18)
A detail account of numerical calculations using Finite-Difference Method (FDM) to calculate the polarization profile in first-order ferroelectric (FE) film system is given. For film, both symmetric and
asymmetric cases ...
Ferroelectric research: the basic fundamental understanding
(Kolej Universiti Kejuruteraan Utara Malaysia, 2005)
This paper gives an overview of the basic theoretical aspect of ferroelectric materials. The basic theoretical concepts are described from the Landau free-energy density F in the first and second-order ferroelectric phase ...
Analysis of Bulk Second-Order Ferroelectric Switching in Oscillatory Dynamical System
(Kolej Universiti Kejuruteraan Utara Malaysia, 2004)
A detailed analysis of polarization reversal in bulk for second-order ferroelectric (FE) phase transition material in the framework of the Landau model is presented. We focus on the changes of polarization P and its switching ...
