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.

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.

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: 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.

This book was released on 2013-11-11 with total page 692 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is a joint effort of the Research Materials Information Center (RMIC) of the Solid State Division at Oak Ridge National Laboratory and the Libraries and Information Systems Center at Bell Telephone Laboratories (BTL) Murray Hill, N. J. The Research Materials Information Center has, since 1963, been answering inquiries on the avail ability, preparation, and properties of inorganic solid-state research materials. The preparation of bibliographies has been essential to this function, and the interest in ferroelectrics led to the compila tion of the journal and report literature on that subject. The 1962 book Ferroelectric Crystals, by Jona and Shirane, was taken as a cutoff point, and all papers through mid-1969 received by the Center have been included. The Libraries and Information Systems Center of BTL has, over a period of years, developed a proprie tary package of computer programs called BELDEX, which formats and generates indexes to biblio graphic material. This group therefore undertook to process RMIC's ferroelectric references by BELDEX so that both laboratories could have the benefit of an indexed basic bibliography in this important research area.

Book excerpt: Barium titanate, a commonly used bulk capacitor has found many interesting applications in the electronics industry. It is widely regarded for its use in capacitance storage devices, DRAM memory application and multi layered ceramic capacitors. Various studies have reported modifications of barium titanate for use in high-k applications and it warrants further interest in exploring various phase transitions of barium titanate thin films. In this study, amorphous to crystalline barium titanate phase transformations are discussed in light of optical properties. These phase transformations are induced during millisecond laser spike annealing of sputtered amorphous barium titanate thin films. Different sputter configurations are adopted in this study namely on-axis, and 90° off-axis. Dwell and peak temperature combinations of laser spike annealing were explored from 250 _s to 10 ms, and 600 °C to 1300 °C respectively. Optical data collection is enabled through high throughput reflectance spectroscopy and the reflectance profile is fitted with an optical model using Transfer Matrix Method (TMM). Based on the model fits, optical thickness decreased at higher dwells and at threshold temperature of 1050 °C for on-axis sputtered barium titanate, and refractive index variation is qualitatively understood across dwell - peak temperature phase map. The Transfer matrix model agrees well with the measured reflectance profiles. Further the TMM indicated that densification occurs at higher peak temperatures giving rise to refractive index and thickness variations across the annealed regions. Also, TMM model fits at onset of crystallization indicated that the amorphous barium titanate undergoes volume expansion prior to nucleation. Correlating with the previous laser spike annealing studies on off-axis barium titanate, it is understood that volume expansion occurs in both off-axis and on-axis sputtered barium titanate during millisecond laser spike annealing, however off-axis sample showed film delamination upon volume expansion whereas this volume expansion phase is stabilized in on-axis sputter configuration.
