Crystal Growth Technology


Book Description

Crystals are the unacknowledged pillars of modern technology. The modern technological developments depend greatly on the availability of suitable single crystals, whether it is for lasers, semiconductors, magnetic devices, optical devices, superconductors, telecommunication, etc. In spite of great technological advancements in the recent years, we are still in the early stage with respect to the growth of several important crystals such as diamond, silicon carbide, PZT, gallium nitride, and so on. Unless the science of growing these crystals is understood precisely, it is impossible to grow them as large single crystals to be applied in modern industry. This book deals with almost all the modern crystal growth techniques that have been adopted, including appropriate case studies. Since there has been no other book published to cover the subject after the Handbook of Crystal Growth, Eds. DTJ Hurle, published during 1993-1995, this book will fill the existing gap for its readers. The book begins with "Growth Histories of Mineral Crystals" by the most senior expert in this field, Professor Ichiro Sunagawa. The next chapter reviews recent developments in the theory of crystal growth, which is equally important before moving on to actual techniques. After the first two fundamental chapters, the book covers other topics like the recent progress in quartz growth, diamond growth, silicon carbide single crystals, PZT crystals, nonlinear optical crystals, solid state laser crystals, gemstones, high melting oxides like lithium niobates, hydroxyapatite, GaAs by molecular beam epitaxy, superconducting crystals, morphology control, and more. For the first time, the crystal growth modeling has been discussed in detail with reference to PZT and SiC crystals.




Comprehensive Semiconductor Science and Technology


Book Description

Semiconductors are at the heart of modern living. Almost everything we do, be it work, travel, communication, or entertainment, all depend on some feature of semiconductor technology. Comprehensive Semiconductor Science and Technology, Six Volume Set captures the breadth of this important field, and presents it in a single source to the large audience who study, make, and exploit semiconductors. Previous attempts at this achievement have been abbreviated, and have omitted important topics. Written and Edited by a truly international team of experts, this work delivers an objective yet cohesive global review of the semiconductor world. The work is divided into three sections. The first section is concerned with the fundamental physics of semiconductors, showing how the electronic features and the lattice dynamics change drastically when systems vary from bulk to a low-dimensional structure and further to a nanometer size. Throughout this section there is an emphasis on the full understanding of the underlying physics. The second section deals largely with the transformation of the conceptual framework of solid state physics into devices and systems which require the growth of extremely high purity, nearly defect-free bulk and epitaxial materials. The last section is devoted to exploitation of the knowledge described in the previous sections to highlight the spectrum of devices we see all around us. Provides a comprehensive global picture of the semiconductor world Each of the work's three sections presents a complete description of one aspect of the whole Written and Edited by a truly international team of experts

Etching of Crystals


Book Description

Defects in Solids, Volume 15: Etching of Crystals: Theory, Experiment, and Application focuses on the processes, reactions, and methodologies involved in the etching of crystals, including thermodynamics and diffusion. The publication first underscores the defects in crystals, detection of defects, and growth and dissolution of crystals. Discussions focus on thermodynamic theories, nature of pit sites, surface roughening during diffusion-controlled dissolution, growth controlled by simultaneous mass transfer and surface reactions, and chemical and thermal etching. The text then examines the theories of dissolution and etch-pit formation and the chemical aspects of the dissolution process, including catalytic reactions, dissolution of semiconductors, topochemical adsorption theories, and diffusion theories. The book tackles the solubility of crystals and complexes in solution and the kinetics and mechanism of dissolution. Topics include metallic crystals, semiconductors, stability of complexes, relationship between solubility, surface energy, and hardness of crystals, and solvents for crystals and estimation of crystal solubility in solvents other than water. The publication is a dependable source of data for readers interested in the etching of crystals.

Additives and Crystallization Processes


Book Description

Crystal growth technology involves processes for the production of crystals essential for microelectronics, communication technologies, lasers and energy producing and energy saving technology. A deliberately added impurity is called an additive and in different industries these affect the process of crystal growth. Thus, understanding of interactions between additives and the crystallizing phases is important in different processes found in the lab, nature and in various industries. This book presents a generalized description of the mechanisms of action of additives during nucleation, growth and aggregation of crystals during crystallization and has received endorsement from the President of the International Organization for Crystal Growth. It is the first text devoted to the role of additives in different crystallization processes encountered in the lab, nature and in industries as diverse as pharmaceuticals, food and biofuels. A unique highlight of the book are chapters on the effect of additives on crystal growth processes, since the phenomena discussed is an issue of debate between researchers

Transparent Semiconducting Oxides


Book Description

This book discusses various aspects of different bulk TSO single crystals in terms of thermodynamics; bulk crystal growth using diverse techniques involving gas phase, solution, and melt; and the resulting crystal size, appearance, and structural quality as well as the fundamental properties that were gathered from bulk single crystals. It presents experimental results accompanied by theoretical results, such as band structure and native defects. Combinations of various bulk single crystals along with their properties show great promise in practical device functionality and fabrication. Many TSO-based devices have already been demonstrated in several technical areas, including electronics, optoelectronics, and photovoltaics as well as sensing devices. The book is the first of its kind that brings together a variety of bulk single crystals of scientifically and technically important TSOs along with their properties, which may result in novel devices with unique functionalities.




Science and Technology of Crystal Growth


Book Description

1. The ninth International Summer School on Crystal Growth. ISSCG IX A complete theory of crystal growth establishes the full dependence of crystal size, shape and structure on external parameters like temperature, pressure, composition, purity, growth rate and stirring of the mother phase, implicitly establishing how the corresponding fields vary in space and time. Such a theory does not exist, however. Therefore equipment to grow crystals is developed on the basis of partial knowledge. Skill, experience and creativity still are of central importance for the success o~ a crystal growth system. In this book we collected contributions from the teachers of the ninth International Summer School on Crystal Growth ISSCG IX, held 11-16 june 1995 at Papendal, the national sports centre of the Netherlands. These contributions were used during the lectures. The authors have tried to present their work in such a way that only basic physical knowledge is required to understand the papers. The book can be used as an introduction to various important sub disciplines of the science and technology of crystal growth. Since, however the information content considerably exceeds a lecture note level and touches the present limits of understanding, it is an up to date handbook as well.
