#### Theoretical investigation of far-infrared optical behaviors in asymmentrical first-order ferroelectrtric thick film

(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 ...

#### 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) ...

#### 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 ...

#### Far-infrared optical transmission through asymmetrical ferroelectric films

(Research India Publications, 2005)

Investigation of far-infrared (FIR) spectroscopy for symmetrical ferroelectric (FE) films are discussed theoretically based on the basis of the Tilley-Zeks (TZ) model using Landau free energy expansion, Landau-
Khalatnikov ...

#### 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 ...
