    Principles and Applications of Ferroelectrics and Related Materials M. E. Lines and A. M. Glass Oxford Classic Texts in the Physical Sciences. This book develops the modern theory of ferroelectricity in terms of soft modes and lattice dynamics and describes modern techniques of measurement, including X-ray, optic, and neutron scattering, infrared absorption, and .   Strain engineering can be used to control the properties of thin-film ferroelectric materials, which are promising for electronic, thermal, Cited by:

    Solid-state physics encompasses experimental and theoretical tools almost as varied as those of all physics. A book which attempts to provide an introduction to such a broad subject is a perilous undertaking, and it is easy to find apparent shortcomings in such a book. An exciton is a bound state of an electron and an electron hole which are attracted to each other by the electrostatic Coulomb is an electrically neutral quasiparticle that exists in insulators, semiconductors and some liquids. The exciton is regarded as an elementary excitation of condensed matter that can transport energy without transporting net electric charge.

    Ferroelectricity, property of certain nonconducting crystals, or dielectrics, that exhibit spontaneous electric polarization (separation of the centre of positive and negative electric charge, making one side of the crystal positive and the opposite side negative) that can be reversed in direction. ran, PHY –Properties of Materials, April Dielectric and Ferroelectric Properties of Materials Dielectric Materials Dielectric means a non-conductor or poor conductor of electricity. Dielectric means a material that presents electric polarization. The dielectric is an insulating material or a very poor conductor of electric current. When dielectrics are placed in an electric.

Ferroelectricity is a characteristic of certain materials that have a spontaneous electric polarization that can be reversed by the application of an external electric field. All ferroelectrics are pyroelectric, with the additional property that their natural electrical polarization is term is used in analogy to ferromagnetism, in which a material exhibits a permanent magnetic ferroelectric: non ferroelectric.

3. Fundamentals of ferroelectricity. There are a number of excellent monographs on ferroelectricity, and the readers can refer to the classical book of Lines and Glass 2 for more information. The defining characteristics of ferroelectrics is the possession of spontaneous polarization P s that can be switched by an external electric field E, resulting in a polarization Cited by: The book by Lines and Glass is the most comprehensive book on the physics of ferroelectrics that I have come across in the pertinent literature.

It is by no means for the novice since a solid background in solid state physics is absoluytely needed. The book especially addresses the lattice dynamics picture of ferroelectricity in a concise by:. In this work ferroelectric domain enhanced electron emission mechanisms are proposed.

The polarization distribution near 90deg domain walls is calculated by solving a set of second order differential equations including the Poisson's one and equations derived from an expansion of the free energy Phi(P) in power series of the polarization according to the Devonshire-Landau .the physics of ferroelectrics.

While there is a fair amount of algebra here and there, none of it is terribly taxing Ü moreover, the algebra is here largely to bolster arguments that can be made mostly in pictures, so if you are happy with the pictures, you have probably got the point.Abstract: Electron emission from ferroelectric cathodes is commonly suggested as an electron source for different application due to its special characteristics such as high current density, easy treatment and operation, : Qiu Ping Wang, Yu Jun Feng, Zhuo Xu, Han Chen Liu.
