Book excerpt: Strontium titanate (STO) is a classical high-permittivity perovskite material known since the 1940s. Although incipient ferroelectric behaviour of SrTiO3 was thoroughly studied during several decades, many new physical phenomena in STO and its solid solutions have been predicted theoretically and observed experimentally in past few years. The obtained results were successfully applied for the development of modern electronic devices on the basis of macroscopic and nanostructured samples. Besides the incipient ferroelectricity, properties of STO include a structural phase transition, semiconductivity, superconductivity, and thermoelectricity, among others. This book provides the latest information on the developments of field preparation, characterization, and application of STO and the materials based on it, with perspectives on future research. It collects the contributions of several established researchers from around the world on the fundamental mechanisms, processing, and possible uses for STO-based materials in the form of single crystals, thin films, and ceramics. This book covers a broad range of topics related to STO and materials based on it, including an overview of lattice dynamics and magnetic resonance characterization, Sr/Ti ratio, and stress induced modification of the properties, modelling, and simulation of improper ferroelectricity and multiferroic phases, dielectric responses and thermoelectric performance for tunable devices, and energy harvesting applications, respectively.

This book was released on 2002-03-22 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first comprehensive guide to the chemicals and gases used in semiconductor manufacturing The fabrication of semiconductor devices involves a series of complex chemical processes such as photolithography, etching, cleaning, thin film deposition, and polishing. Until now, there has been no convenient source of information on the properties, applications, and health and safety considerations of the chemicals used in these processes. The Handbook of Chemicals and Gases for the Semiconductor Industry meets this need. Each of the Handbook's eight chapters is related to a specific area of semiconductor processing. The authors provide a brief overview of each step in the process, followed by tables containing physical properties, handling, safety, and other pertinent information on chemicals and gases typically used in these processes. The 270 chemical and gas entries include data on physical properties, emergency treatment procedures, waste disposal, and incompatible materials, as well as descriptions of applications, chemical mechanisms involved, and references to the literature. Appendices cross-reference entries by process, chemical name, and CAS number. The Handbook's eight chapters are: Thin Film Deposition Materials Wafer Cleaning Materials Photolithography Materials Wet and Dry Etching Materials Chemical Mechanical Planarizing Methods Carrier Gases Uncategorized Materials Semiconductor Chemicals Analysis No other single source brings together these useful and important data on chemicals and gases used in the manufacture of semiconductor devices. The Handbook of Chemicals and Gases for the Semiconductor Industry will be a valuable reference for process engineers, scientists, suppliers to the semiconductor industry, microelectronics researchers, and students.

Available in PDF, EPUB and Kindle. Book excerpt: This handbook--a sequel to the widely used Handbook of Optical Constants of Solids--contains critical reviews and tabulated values of indexes of refraction (n) and extinction coefficients (k) for almost 50 materials that were not covered in the original handbook. For each material, the best known n and k values have been carefully tabulated, from the x-ray to millimeter-wave region of the spectrum by expert optical scientists. In addition, the handbook features thirteen introductory chapters that discuss the determination of n and k by various techniques. * Contributors have decided the best values for n and k * References in each critique allow the reader to go back to the original data to examine and understand where the values have come from * Allows the reader to determine if any data in a spectral region needs to be filled in * Gives a wide and detailed view of experimental techniques for measuring the optical constants n and k * Incorporates and describes crystal structure, space-group symmetry, unit-cell dimensions, number of optic and acoustic modes, frequencies of optic modes, the irreducible representation, band gap, plasma frequency, and static dielectric constant

Available in PDF, EPUB and Kindle. Book excerpt: Strontium titanate is a material of considerable interest, with many applications. Though it has been extensively studied experimentally and computationally, there are unresolved issues regarding the structure and defect properties. Experimental examination is challenging due to the propensity of the material to form small domains. Even when single crystals are available, the observed behaviour is an average of these local domains. In this thesis we undertook an extensive computational investigation of strontium titanate. The material is known to undergo a second order phase transition from cubic (Pm-3m) to tetragonal (I4/mcm) at ~105 K. We began the investigation by examining the tetragonal phase. Using plane-wave DFT with the LDA, PBE and PBEsol density functionals, we mapped out in three dimensions the I4/mcm space group and fitted the resultant potential energy surfaces to polynomials. Extensive analysis was performed and expectation values for the 0 K octahedral rotation angle were calculated as being between 4.6° and 6.1° for the three functionals. We continued by carrying out an extensive study, where we examined many different low symmetry saddle points, and minima using the PBEsol functional (which was found to have produced the best results). A total of 38 structures (many of which are unique) were examined in detail and the vibrational and imaginary modes involved in the transitions between higher and lower symmetry structures were identified and described. We identified the lowest energy structure as being monoclinic, with a rhombohedral structure at slightly higher energy. We also note that, as the energy differences are so small between these lower symmetry structures (~0.1 meV per formula unit), it is unlikely that these phases will appear in nature. In the final results chapter we present three new sets of classical pair potentials for modelling strontium titanate. We applied these potentials to model vacancy type defects and investigated the transition pathway for oxygen and strontium migration between adjacent sites. We calculated migration barriers of between 0.96 and 1.35 eV for oxygen and between 3.17 and 3.20 eV for strontium, which are improved estimates over previous pair potential results.
