Download or read book Theoretical Studies of the Chemistry and Physics of Oxygen in Silicon written by Lawrence C. Snyder and published by . This book was released on 1988 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have developed a cyclic-cluster program to compute the structure and properties of defects in crystalline solids. We have found the semi-empirical electronic structure method MINDO/3 to give the best account of the structure, stability and states near the gap for defects in silicon. We have applied the cyclic cluster program to describe the chemistry and physics of hydrogen and oxygen in a silicon crystal. We have concluded that a di-ylid is a promising candidate for the core of the 450 oxygen thermal donor in silicon. We have discovered that a four-member ring containing two oxygen atoms is likely to diffuse much faster than interstitial oxygen in silicon. We have applied perturbation theory to give a qualitative explanation of the ladder of effective mass states associated with oxygen clusters in silicon and germanium. Keywords: Semiconductor theory, Silicon defects, Oxygen thermal donors. (JES).

Book excerpt: On the theoretical side, a new highly scalable code for frozen core second order perturbation theory gradients for closed shell molecules has been developed. The development of analogous codes for molecules with unpaired electrons is in progress. A sequential unrestricted code for this purposed has been completed. The derivation for the spin-restricted open shell second order perturbation theory gradients has been completed, and a paper describing this derivation has now been accepted. Other important developments are new convergence methods for MCSCF wave functions that facilitate MCSCF calculations on large molecules, the derivation of gradients for multi-reference second order perturbation theory, the development and implementation of a full-CI method that is amenable to parallelization, further developments of our effective fragment potential (EFP) method for studying solvation and liquid behavior, the development of molecular dynamics and Monte Carlo methods to facilitate the study of solvation and liquid behavior, the development and implementation of a new method for producing global potential energy surfaces from sets of ab initio points, the development and implementation of both grid-based and gridless approaches to density functional theory, and the development and implementation of several MCSCF-based approaches to spin-orbit coupling. With regard to applications, considerable progress has been made in our understanding of the mechanisms for formation of POSS (polyhedral oligomeric silsesquioxanes) and the possibility of passing small gas molecules though them. POSS titanium analogs have also been studied, as have the hydrosilation and bis-silylation reactions. Other applications include studies of surface chemistry, several silicon systems and studies of the behavior of water clusters.

This book was released on 1993 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this project were to study a variety of main group compounds and their reactions, with special emphasis on the chemistry of silicon and how the behavior of this element relates to problems of Air Force interest. The process investigated included the detailed mechanism of the chemical vapor deposition (CVD) process, the polymerization mechanism of silanols, the role of hypervalent silicon in polymerization mechanisms, and the relationship of hypervalent silicon to hypervalent aluminum. Toward the end of the project, the effort broadened into investigations of the interactions of silicon with transition metals, in view of the role of the transition metals as catalysts in a variety of reactions. The second main area of investigation has been the design and study of high energy content molecules, with the intent of designing new potentially higher energy fuels. One compound that had been previously proposed by others, the asymmetric dimer of NO, was shown by us to predissociate. So, this compound will not be a realistic HEDM compound. We think, however, that other isomers of the NO dimer have greater potential for new fuels, and these possibilities will be explored.

Download or read book Organosilicon Compounds written by Vladimir Ya Lee and published by Academic Press. This book was released on 2017-08-22 with total page 758 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organosilicon Compounds: Theory and Experiment (Synthesis), volume 1, comprises two parts. The first part, Theory, covers state-of-the-art computational treatments of unusual nonstandard organosilicon compounds that classical bonding theory fails to describe adequately. The second part, Experiment (Synthesis), describes recent synthetic advances in the preparation of a variety of organosilicon compounds with different coordination numbers of the central silicon: from tetracoordinate to low-coordinate to hypercoordinate derivatives. Organosilicon Compounds: From Theory to Synthesis to Applications provides a comprehensive overview of this important area of organic and organometallic chemistry, dealing with compounds containing carbon–silicon bonds. This field, which includes compounds that are widely encountered in commercial products such as in the fabrication of sealants, adhesives, and coatings, has seen many milestone discoveries reported during the last two decades. Beginning with the theoretical aspects of organosilicon compounds' structure and bonding, the book then explores their synthetic aspects, including main group element organosilicon compounds, transition metal complexes, silicon cages and clusters, low-coordinate organosilicon derivatives (cations, radicals, anions, multiple bonds to silicon, silaaromatics), and more. Next, readers will find valuable sections that explore physical and chemical properties of organosilicon compounds by means of X-ray crystallography, 29Si NMR spectroscopy, photoelectron spectroscopy, and other methods. Finally, the work delves into applications for industrial uses and in many related fields, such as polymers, material science, nanotechnology, bioorganics, and medicinal silicon chemistry. - Features valuable contributions from prominent experts that cover both fundamental (theoretical, synthetic, physico-chemical) and applied (material science, applications) aspects of modern organosilicon chemistry - Covers important breakthroughs in the field, along with the historically significant achievements of the past - Includes applied information for a wide range of specialists, from junior and senior researchers (from both academia and industry) - Ideal reference for those working in organometallic, organosilicon, main group element, transition metal, and industrial silicon chemistry, as well as those from interdisciplinary fields, such as polymer, material science, and nanotechnology

Download or read book Progress in Organosilicon Chemistry written by Bogdan Marciniec and published by Taylor & Francis. This book was released on 1995 with total page 620 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progress in Organosilicon Chemistry comprises more than thirty papers presented by many of the world's most eminent organosilicon specialists at the Tenth International Symposium on Organosilicon Chemistry held in Poznan, Poland in August 1993. The conference marked the fiftieth anniversary of the discovery and exploration of "direct synthesis." As much attention today is directed beyond silicon polymers, chemists have become involved with the use of elementary silicon and its applications, including ultrapure silicon in transistors and computers, silicon precursors of polymers, and other silicon-based materials as well as fine chemicals. This book provides an overview of organosilicon chemistry, including organic and inorganic chemistry of silicon, silicon polymers and oligomers; theoretical and structural chemistry of silicon; silicon-based materials and their applications; silicon in organic synthesis; mechanistic organosilicon chemistry; and bio- and environmental organosilicon chemistry. This diverse range of topics makes the book a valuable reference for chemists working in both applied and theoretical chemistry.
