This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The electro-optic properties of epitaxial BaTiO3 and KTa xNb1-xO3 thin films were investigated to determine their utility as the active medium in electro-optic (EO) devices. The relationship between the EO properties, both static and dynamic, and the ferroelectric (FE) domain structure of the films was determined. A theoretical model was developed to describe the magnitude and dynamic response of the EO effect and dielectric properties of multidomain FE films. The effective linear EO coefficient of each film, reff, was modeled as a linear superposition of the EO response of each FE domain variant, and the dynamic EO response was described in terms of a statistical distribution of domain relaxation times.

Available in PDF, EPUB and Kindle. Book excerpt: Mechanic and Dielectric Properties deals with the mechanical and dielectric properties of thin films. Topics covered range from the deposition and mechanical properties of superlattice thin films to the preparation of hard coatings by sputtering and arc evaporation. The use of thin films in microwave acoustics is also discussed, along with ferroelectric films for integrated electronics and the physics, chemistry, and technology of electrochromic tungsten-oxide-based thin films. Comprised of five chapters, this volume begins with an analysis of the growth, characterization, and mechanical behavior of films comprising multilayers primarily of metal and refractory metallic compound components. The next chapter reviews the mechanical properties of hard coatings prepared by sputtering and arc evaporation, together with the influence of multilayer and gradient structures, and of film crystallinity, crystal orientation, and morphology, on properties such as hardness, coating smoothness, and friction behavior. Subsequent chapters focus on the unique role played by piezoelectric films in signal processing devices utilizing bulk or surface acoustic waves; the properties and applications of ferroelectric films in integrated electronics; and the underlying physics and chemistry of electrochromic tungsten-oxide-based thin films. This book should be of interest to physicists.

Download or read book Ferroelectric Thin Films written by Carlos Paz de Araujo and published by Taylor & Francis US. This book was released on 1996 with total page 598 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impetus for the rapid development of thin film technology, relative to that of bulk materials, is its application to a variety of microelectronic products. Many of the characteristics of thin film ferroelectric materials are utilized in the development of these products - namely, their nonvolatile memory and piezoelectric, pyroelectric, and electro-optic properties. It is befitting, therefore, that the first of a set of three complementary books with the general title Integrated Ferroelectric Devices and Technologies focuses on the synthesis of thin film ferroelectric materials and their basic properties. Because it is a basic introduction to the chemistry, materials science, processing, and physics of the materials from which integrated ferroelectrics are made, newcomers to this field as well as veterans will find this book self-contained and invaluable in acquiring the diverse elements requisite to success in their work in this area. It is directed at electronic engineers and physicists as well as process and system engineers, ceramicists, and chemists involved in the research, design, development, manufacturing, and utilization of thin film ferroelectric materials.

This book was released on 2013-11-27 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past five years have witnessed some dramatic developments in the general area of ferroelectric thin films materials and devices. Ferroelectrics are not new materials by any stretch ofimagination. Indeed, they have been known since the early partofthis century and popular ferroelectric materials such as Barium Titanate have been in use since the second world war. In the late sixties and seventies, a considerable amountofresearch and development effort was made to create a solid state nonvolatile memory using ferroelectrics in a vary simple matrix-addressed scheme. These attempts failed primarily due to problems associated with either the materials ordue to device architectures. The early eighties saw the advent of new materials processing approaches, such as sol-gel processing, that enabled researchers to fabricate sub-micron thin films of ferroelectric materials on a silicon substrate. These pioneering developments signaled the onsetofa revival in the areaofferroelectric thin films, especially ferroelectric nonvolatile memories. Research and development effort in ferroelectric materials and devices has now hit a feverish pitch, Many university laboratories, national laboratories and advanced R&D laboratories oflarge IC manufacturers are deeply involved in the pursuit of ferroelectric device technologies. Many companies worldwide are investing considerable manpower and resources into ferroelectric technologies. Some have already announced products ranging from embedded memories in micro controllers, low density stand-alone memories, microwave circuit elements, andrf identification tags. There is now considerable optimism that ferroelectric devices andproducts will occupy a significant market-share in the new millennium.

Download or read book Growth of Ferro Electric Tungsten Bronze Epitaxial Thin Films for Electro Optic Device Applications written by R. R. Neurgaonkar and published by . This book was released on 1986 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strontium Barium Biobates:60 doped with Ce and Fe crystals have now been grown with improved optical quality using the Czochralski technique. The liquid phase epitaxial (LPE) growth of SBN:46 on SBN:60 substrate has also been successfully demonstrated, with particularly good results for (100) and (110) film orientations. The recent photorefractive measurements on Ce doped SBN:60 crystals show that the Tungsten Bronze, SBN:60 crystals are superior in many respects to BaTi03 because of enhanced two beam coupling coefficients, sensitivity and the overall flexibility of tungsten bronze crystals. La3+-doped SBN:50 single crystals have also been grown for pyroelectric detector studies and it was found that the growth of doped crystals is possible. Crystals as large as 1 to 1.5 cm in diameter have been grown successfully. Current measurements show that this composition exhibits excellent pyroelectric and dielectric properties to use in longitudinal configuration; hence, work is in progress to use this composition for pyroelectric detector applications. The role of other cations such as calcium and yttrium has also been studied and they appear to be promising for the proposed device applications.

Download or read book Ferroelectricity at the Nanoscale written by Vladimir Fridkin and published by Springer Science & Business Media. This book was released on 2013-10-25 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The investigation of nanosized ferroelectric films and ferroelectric nanocrystals has attracted much attention during the past 15 – 20 years. There is interest in the fundamental and applied aspects. The theoretical basis is connected with the development of the Landau-Ginzburg-Devonshire (LGD) mean field and the first principles theories to the ultrathin ferroelectric films with thickness in the vicinity of critical size. Important potential applications are possible nanosize ferroelectric films in non-volatile memories, microelectronics, sensors, pyroelectric and electro-optic devices. This new area of research of ferroelectricity is still in impetuous development and far from completion. Many topics elucidated need generalization. The book contains theory and experimental data for a wide range of ferroelectric materials.

Available in PDF, EPUB and Kindle. Book excerpt: Our understanding and control of epitaxial oxide heterostructures has progressed along multiple frontiers including magnetic, dielectric, ferroelectric, and superconducting oxide materials. This has resulted in both independent rediscovery and the successful borrowing of ideas from ceramic science, solid-state physics, and semiconductor epitaxy. A new field of materials science has emerged which aims at the use of the intrinsic properties of various oxide materials in single-crystal thin-film form. Exploiting the potential of these materials, however, will only be possible if many fundamental and engineering questions can be answered. This book represents continued progress toward fulfilling that promise. Technical information on epitaxial oxide thin films from industry, academia and government laboratories is presented. Topics include: dielectrics; ferroelectrics; optics; superconductors; magnetics; magnetoresistance.

Download or read book Growth Characterization and Applications of Multifunctional Ferroelectric Thin Films written by Bo Xiao and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Ferroelectric materials have been extensively studied theoretically and experimentally for many decades. Their ferroelectric, piezoelectric, pyroelectric, dielectric and electro-optical properties offer great promise in various applications such as non-volatile random access memory devices, non linear optics, motion and thermal sensors, and tunable microwave devices. Advanced applications for high dielectric constant insulators and nonvolatile memories in semiconductor industry have led to a meteoric rise of interest in the ferroelectrics recently. As most studied and technically important ferroelectric materials, lead zirconate titanate (PZT) and barium strontium titanate (BST) are widely investigated to understand their properties for potential device applications. Using radio frequency magnetron sputtering, single crystalline PZT and BST thin films have been achieved on SrTiO3 substrates, and been characterized for their structural and electrical properties. Eyeing their different potential applications, ferroelectric, pyroelectric and dielectric properties of PZT and BST thin films were studied. In addition, the introduction of bridge layers (nucleation or buffer layers) grown by molecular beam epitaxy (MBE) has been employed to facilitate the heterostructure growth of PZT thin films on GaN and BST thin films on sapphire substrates. Highly (111)-oriented perovskite PZT thin films were achieved on silicon-doped GaN (0001)/c-sapphire with a PbTiO3/PbO oxide bridge layer. And (001)-oriented BST thin films were grown on a-plane sapphire with an MgO/ZnO bridge layer. This dissertation also discusses the realization of PZT ferroelectric field effect transistors (FeFET). Two different 1T FeFET structures were successfully fabricated and their electrical properties were examined. Ferroelectric behavior was observed in the plot of source-drain current versus gate voltage where it exhibited a large counterclockwise hysteresis with 50% current modulation.
