    • 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 ...
    • 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 ...

    • 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) ...
