The phenomenological theory of Far-Infrared spectroscopy for a ferroelectric fim system
(Malaysian Institute of Physics & National University of Malaysia, 2004-10-05)
We describe a detailed phenomenological theory of far-infrared (FIR) spectroscopy in symmetric and asymmetric ferroelectric (FE) film for the second and first-order phase transition. For the asymmetric FE film, a silicon ...
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 ...
Oscillatory dynamical switching system of bulk ferroelectrics
(Science Publications, 2005)
This study gives a detailed account of calculation of the bulk ferroelectric (FE) oscillatory dynamical system switching for first and second-order phase transition, respectively. All the formalism is delineated in the ...
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 ...
