Available in PDF, EPUB and Kindle. Book excerpt: The physical and electrical properties of barium titanate films approximately 1 micrometer thick, prepared by rf sputtering onto silicon substrates in both pure argon and 95% argon-5% oxygen glow discharges were investigated. The deposition rate, crystal structure, and refractive index of the films were investigated as a function of deposition temperature and sputtering gas. The electrical characteristics of the films, including the dielectric constant, loss tangent, conductivity, insulator bulk charge, charge storage at the BaTiO3-SiO2 interface, and ferroelectricity were also investigated.

Available in PDF, EPUB and Kindle. Book excerpt: Structural, chemical, dielectric, and ferroelectric (limited) characteristics of RF sputtered barium titanate (BaTiO3) are described. Primary interest was to determine film capability for providing high capacitance devices for hybrid and thin film integrated circuits. The extent of ferroelectric film behavior was also of concern for charge storage use in the development of thin film image plates for miniature solid state facsimile cameras. Metal-dielectric-metal capacitor structures incorporating amorphous or polycrystalline BaTiO3 films were fabricated and evaluated. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Research on ferroelectricity and ferroelectric materials started in 1920 with the discovery by Valasek that the variation of spontaneous polarization in Rochelle salt with sign and magnitude of an applied electric field traced a complete and reproducible hysteresis loop. Activity in the field was sporadic until 1935, when Busch and co-workers announced the observation of similar behavior in potassium dihydrogen phosphate and related compounds. Progress thereafter continued at a modest level with the undertaking of some theoretical as well as further experimental studies. In 1944, von Hippel and co-workers discovered ferroelectricity in barium titanate. The technological importance of ceramic barium titanate and other perovskites led to an upsurge of interest, with many new ferroelectrics being identified in the following decade. By 1967, about 2000 papers on various aspects of ferroelectricity had been published. The bulk of this widely dispersed literature was concerned with the experimental measurement of dielectric, crystallographic, thermal, electromechanical, elastic, optical, and magnetic properties. A critical and excellently organized cpmpilation based on these data appeared in 1969 with the publica tion of Landolt-Bornstein, Volume 111/3. This superb tabulation gave instant access to the results in the literature on nearly 450 pure substances and solid solutions of ferroelectric and antiferroelectric materials. Continuing interest in ferroelectrics, spurred by the growing importance of electrooptic crystals, resulted in the publication of almost as many additional papers by the end of 1969 as had been surveyed in Landolt-Bornstein.

This book was released on 1981 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data is presented on BaTiO3 films which were rf sputtered on Pt, quartz and sapphire substrates at various temperatures and gas mixtures. Measurements of density, dielectric constant, electrical conductivity, X-ray diffraction, energy band gap from optical absorption and wavelength, and temperature dependence of refractive index are presented. Measurements were also made on a BaTiO3 single crystal and a hot-pressed ceramic pellet for direct comparison of bulk properties to those of the films. The results of this work demonstrate that a transition of the properties occurs between the amorphous and crystalline states depending on the surface temperature during sputtering. The transition is sluggish up to 700 C above which crystalline properties of the films appear rapidly. (Author).

Book excerpt: Barium titanate and barium strontium titanate thin films were deposited on base metal foils via chemical solution deposition and radio frequency magnetron sputtering. The films were processed at elevated temperatures for densification and crystallization. Two unifying research goals underpin all experiments: 1) To improve our fundamental understanding of complex oxide processing science, and 2) to translate those improvements into materials with superior structural and electrical properties. The relationships linking dielectric response, grain size, and thermal budget for sputtered barium strontium titanate were illustrated. (Ba0.6Sr0.4)TiO3 films were sputtered on nickel foils at temperatures ranging between 100-400 Ã'°C. After the top electrode deposition, the films were co-fired at 900 Ã'°C for densification and crystallization. The dielectric properties were observed to improve with increasing sputter temperature reaching a permittivity of 1800, a tunability of 10:1, and a loss tangent of less than 0.015 for the sample sputtered at 400 Ã'°C. The data can be understood using a brick wall model incorporating a high permittivity grain interior with low permittivity grain boundary. However, this high permittivity value was achieved at a grain size of 80 nm, which is typically associated with strong suppression of the dielectric response. These results clearly show that conventional models that parameterize permittivity with crystal diameter or film thickness alone are insufficiently sophisticated. Better models are needed that incorporate the influence of microstructure and crystal structure. This thesis next explores the ability to tune microstructure and properties of chemically solution deposited BaTiO3 thin films by modulation of heat treatment thermal profiles and firing atmosphere composition. Barium titanate films were deposited on copper foils using hybrid-chelate chemistries. An in-situ gas analysis process was developed to probe the organic removal and.

Available in PDF, EPUB and Kindle. Book excerpt: Titanate-centered perovskites are an important class of crystalline materials with outstanding structural and property tunability. Recently, titanate perovskites have been extensively investigated as new-generation materials for various energy-allied applications, together with photovoltaic cells, light emitting diodes, photo detectors and lasers, for their exceptional optical and electronic properties. With increasing attention on the development of nanotechnology and multidisciplinary research, scientists have been trying to downscale the titanate perovskite structures into the nanoregime, so as to further boost their performances and applications. Compared with bulk perovskite materials, perovskite nanomaterials exhibit a series of advantages, such as fabrication of thin films and flexible devices and PNMs display high process ability. Perovskite nanomaterials feature rich and controllable facets and active sites. Besides benefiting from the small-size effect and quantum effect, perovskite nanomaterials are endowed with outstanding photo-electromagnetic properties. Furthermore, the applications of titanate-centered perovskites in the fields of energy, environment, WLEDs, forensic science and piezoelectric devices will be reviewed. This book will also discuss the possible solutions to the problems in their application by optimizing their compositions, structures and preparation methods. This book will systematically summarize the key points in the design, synthesis, property improvements and application expansion of titanate-centered perovskites. The different perovskite structures and the rational design of functional materials will be discussed in detail. The advantages, disadvantages and experimental parameters of different synthesis methods for titanate-centered perovskites will be reviewed. This book will also summarize some practical experiences in selecting suitable elements and designing multifunctional materials according to the mechanisms and principles of elements promoting the properties of perovskites by covering almost last 20 years of literature. At the end of this book, we will provide an outlook on the opportunities and challenges in the view of development in titanate-centered perovskites The inclusive effectiveness and practicality of prospective titanate energy materials and systems are directly connected to many materials-related factors. This volume of book features totally seven sections that envelop a wide range of titanate energy materials. They cover the modern developments involving materials for alternative and renewable energy sources and systems, including energy storage and batteries, nanocomposites, hydrogen, solar, wind, geothermal, biomass and nuclear. The book is a significant orientation for students and researchers (from academics, but also industry) interested in understanding the properties of emerging titanate energy materials and challenges in the recent era.
