Analysis of Bulk Second-Order Ferroelectric Switching in Oscillatory Dynamical System
Mohamad Nazri, Abdul Halif; Junaidah, Osman (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 ... -
A numerical approach of Polarization profile for First-Order Ferroelectric film system using Finite-Difference method
Mohamad Nazri, Abdul Halif; Junaidah, Osman (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 ... -
The phenomenological theory of Far-Infrared spectroscopy for a ferroelectric fim system
Mohamad Nazri, Abdul Halif; K.H. Chew; Tilley, David R.; Junaidah, Osman (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 ... -
Polarization reversal of Bulk Ferroelectrics
Mohamad Nazri, Abdul Halif; Junaidah, Osman (Kolej Universiti Kejuruteraan Utara Malaysia, 2005-05-18)This paper gives a detail formalism and analysis for polarization switching in oscillatory dynamical systems for bulk first-order ferroelectric (FE) phase transition on the basis of Kolmogorov-Avrami (KA) model. We are ... -
Surface state on first-order ferroelectrics
Junaidah, Osman; Tilley, David Reginald; Rosy, Teh; Ishibashi, Y.; Mohamad Nazri, Abdul Halif; Khian, Hooi Chew (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) ... -
Theoretical investigation of far-infrared optical behaviors in asymmentrical first-order ferroelectrtric thick film
Mohamad Nazri, Abdul Halif; Khian Hooi, Chew; David R., Tilley; Junaidah, Osman (Universiti Putra Malaysia (UPM), 2005-12-06)This paper gives a detailed, fully numerical approach to investigate the behavior of far-infrared (FIR) waves in the first-order of asymmetrical thick film ferroelectrics on semiconductor substrate. The theoretical calculation ...
