    • 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 ...
    • Ferroelectric research: the basic fundamental understanding 

      Mohamad Nazri, Abdul Halif (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 ...
    • 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 ...
    • Oscillatory dynamical switching system of bulk ferroelectrics 

      Mohamad Nazri, Abdul Halif; S. Daud; Junaidah Osman (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 ...
    • 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 ...
