Book Synopsis Non-Classical Crystallization of Thin Films and Nanostructures in CVD and PVD Processes by : Nong Moon Hwang
Download or read book Non-Classical Crystallization of Thin Films and Nanostructures in CVD and PVD Processes written by Nong Moon Hwang and published by Springer. This book was released on 2016-06-14 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive introduction to a recently-developed approach to the growth mechanism of thin films and nanostructures via chemical vapour deposition (CVD). Starting from the underlying principles of the low pressure synthesis of diamond films, it is shown that diamond growth occurs not by individual atoms but by charged nanoparticles. This newly-discovered growth mechanism turns out to be general to many CVD and some physical vapor deposition (PVD) processes. This non-classical crystallization is a new paradigm of crystal growth, with active research taking place on growth in solution, especially in biomineralization processes. Established understanding of the growth of thin films and nanostructures is based around processes involving individual atoms or molecules. According to the author’s research over the last two decades, however, the generation of charged gas phase nuclei is shown to be the rule rather than the exception in the CVD process, and charged gas phase nuclei are actively involved in the growth of films or nanostructures. This new understanding is called the theory of charged nanoparticles (TCN). This book describes how the non-classical crystallization mechanism can be applied to the growth of thin films and nanostructures in gas phase synthesis. Based on the author’s graduate lecture course, the book is aimed at senior undergraduate and graduate students and researchers in the field of thin film and nanostructure growth or crystal growth. It is hoped that a new understanding of the growth processes of thin films and nanostructures will reduce trial-and-error in research and in industrial fabrication processes.

Book Synopsis Handbook of Physical Vapor Deposition (PVD) Processing by : D. M. Mattox
Download or read book Handbook of Physical Vapor Deposition (PVD) Processing written by D. M. Mattox and published by Cambridge University Press. This book was released on 2014-09-19 with total page 947 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers all aspects of physical vapor deposition (PVD) process technology from the characterizing and preparing the substrate material, through deposition processing and film characterization, to post-deposition processing. The emphasis of the book is on the aspects of the process flow that are critical to economical deposition of films that can meet the required performance specifications. The book covers subjects seldom treated in the literature: substrate characterization, adhesion, cleaning and the processing. The book also covers the widely discussed subjects of vacuum technology and the fundamentals of individual deposition processes. However, the author uniquely relates these topics to the practical issues that arise in PVD processing, such as contamination control and film growth effects, which are also rarely discussed in the literature. In bringing these subjects together in one book, the reader can understand the interrelationship between various aspects of the film deposition processing and the resulting film properties. The author draws upon his long experience with developing PVD processes and troubleshooting the processes in the manufacturing environment, to provide useful hints for not only avoiding problems, but also for solving problems when they arise. He uses actual experiences, called ""war stories"", to emphasize certain points. Special formatting of the text allows a reader who is already knowledgeable in the subject to scan through a section and find discussions that are of particular interest. The author has tried to make the subject index as useful as possible so that the reader can rapidly go to sections of particular interest. Extensive references allow the reader to pursue subjects in greater detail if desired. The book is intended to be both an introduction for those who are new to the field and a valuable resource to those already in the field. The discussion of transferring technology between R&D and manufacturing provided in Appendix 1, will be of special interest to the manager or engineer responsible for moving a PVD product and process from R&D into production. Appendix 2 has an extensive listing of periodical publications and professional societies that relate to PVD processing. The extensive Glossary of Terms and Acronyms provided in Appendix 3 will be of particular use to students and to those not fully conversant with the terminology of PVD processing or with the English language.

Book Synopsis Crystallization and Growth of Colloidal Nanocrystals by : Edson Roberto Leite
Download or read book Crystallization and Growth of Colloidal Nanocrystals written by Edson Roberto Leite and published by Springer Science & Business Media. This book was released on 2011-11-17 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the size, shape, and microstructure of nanocrystalline materials strongly impact physical and chemical properties, the development of new synthetic routes to nanocrystals with controlled composition and morphology is a key objective of the nanomaterials community. This objective is dependent on control of the nucleation and growth mechanisms that occur during the synthetic process, which in turn requires a fundamental understanding of both classical nucleation and growth and non-classical growth processes in nanostructured materials. Recently, a novel growth process called Oriented Attachment (OA) was identified which appears to be a fundamental mechanism during the development of nanoscale materials. OA is a special case of aggregation that provides an important route by which nanocrystals grow, defects are formed, and unique—often symmetry-defying—crystal morphologies can be produced. This growth mechanism involves reversible self-assembly of primary nanocrystals followed by reorientation of the assembled nanoparticles to achieve structural accord at the particle-particle interface, the removal of adsorbates and solvent molecules, and, finally, the irreversible formation of chemical bonds to produce new single crystals, twins, and intergrowths. Crystallization and Growth of Colloidal Nanocrystals provides a current understanding of the mechanisms related to nucleation and growth for use in controlling nanocrystal morphology and physical-chemical properties, and is essential reading for any chemist or materials scientist with an interest in using nanocrystals as building blocks for larger structures. This book provides a compendium for the expert reader as well as an excellent introduction for advanced undergraduate and graduate students seeking a gateway into this dynamic area of research.

Available in PDF, EPUB and Kindle. Book excerpt: In the past 50 years thin-film technologies, ranging from deposition techniques to their applications have been rapidly developed in the industrial field. Although we are not directly exposed to such technologies, they have become indispensable to the progress of human life. This book deals with a unique collection of deposition techniques and their state-of-the-art applications. Among various thin-film deposition technologies, physical vapor deposition (PVD) and chemical vapor deposition (CVD) techniques are widely used in the deposition of thin-films ranging from semiconductors to decorative coatings. A variety of all types of PVD and CVD processes are used to deposit single- or multilayered coatings in the thickness range of a few nanometers to several microns. In chapter 1, modern PVD technologies such as reactive magnetron sputtering, arc source deposition, pulsed laser ablation deposition, and ion plating are reviewed in order to understand their concept and mechanism. In particular, the review is focused on the recent developments of plasma- and ion-assisted PVD processes and their properties and applications. In chapter 2, the CVD process, particularly metal organic chemical vapor deposition (MOCVD), is introduced. In this chapter, the basic concept of MOCVD as a promising deposition technique and the fabrication of ZnO thin-films using MOCVD are presented. Zinc oxide (ZnO) has been considered to be a promising material for optoelectronic, spintronic, and nanostructure devices and other applications because of its wide direct bandgap and large exciton binding energy. Currently it is used in blue-light-emitting devices and laser applications. This use of ZnO in such applications has been made possible by MOCVD and molecular beam epitaxy (MBE) techniques. Thin-films such as metals or oxides could be deposited by electrochemical methods. Chapter 3 describes a novel approach to the fabrication of thin-film metal oxides such as Cu2O, PbO2, and ZnO by two distinct electrochemical techniques of deposition and anodization. Some polymers are selected as applications of thin-films. The fabrication of polymer thin-films using vacuum technologies offers many advantages such as excellent step coverage in three-dimensional structures, physicochemical stability, and easy control of thickness. Furthermore, this fabrication process does not require liquid solvents and is essentially a dry process. Basically, polymers are formed on the surface of a surface by reaction with radicals generated by thermal energy. Chapter 4 introduces the principle of the deposition process of parylene polymer thin-films as a type of thermal CVD technique along with its properties and application fields. Chapter 5 gives an overview of the state-of-the-art applications of photocatalytic TiO2 thin-films. TiO2 is a wide bandgap semiconductor, which has become a well-known photoactivated catalyst for water and air purification and self-cleaning surfaces. In this chapter, an introduction to the activity of TiO2 including important factors that determine the photocatalytic activity, deposition techniques, and general considerations are presented. Thin-film deposition processes such as sputtering, MOCVD, and plasma etching could be useful techniques for the fabrication of perovskite ceramic oxide thin-films, which are used in non-volatile memory chips and piezoelectric devices in micro electro mechanical system (MEMS) applications. Chapter 6 describes thin-film technologies for the fabrication of perovskite ceramic oxide thin-films and explores key technologies for their production and integration and improvements for their performances. Display technology has enhanced rapidly due to the urgent requirement of thin, light-weight, and high-performance devices that consume low power consuming for receiving and transmitting information anywhere and at any time. Organic light-emitting devices (OLEDs) have attracted attention in recent years because of their applications in displays. Top-emission OLEDs have been recognized as applications of thin-film technology. In chapter 7, transparent cathodes for top emission OLEDs are reviewed. Since, it is necessary to perform a proper analysis in thin-film technology, the use of TEM for such analysis is reviewed in chapter 8. For more than 30 years, TEM has been employed as a powerful analytical technique for nanoscale materials. Currently, it is the most widely used method for structural analysis of thin-films. Although TEM observations provide a considerable amount of information, it is difficult to prepare TEM samples by conventional ion milling techniques. A recently developed focused ion beam (FIB) technique has enabled us to reduce the long sample preparation time, resulting in the extension of analytical TEM fields to material sciences. This chapter explains the TEM sample preparation method using FIB milling and its recent applications. Finally, thin-film technologies that are expected to develop new cathode and anode materials with arbitrary compositions as well as the mechanism in lithium batteries are introduced in chapter 9. Thin-films can play an important role in lithium batteries. This chapter describes the preparation of cathode and anode thin-film electrodes by a suitable deposition technique, characterization of the thin-film structure, electrochemical characterization in lithium cells, and relationship between micro- and macroscale electrochemical characteristics of the electrode materials. It is hoped that this book will provide valuable information to readers who are interested in thin-film technology and its application fields. Finally, I would like to acknowledge all the authors who have contributed to this review book.
Book Synopsis Formation and Temperature Stability of the Liquid Phase in Thin-Film Systems by : Serhii Dukarov
Download or read book Formation and Temperature Stability of the Liquid Phase in Thin-Film Systems written by Serhii Dukarov and published by Springer Nature. This book was released on 2023-11-25 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a summary of the topic of supercooling during crystallization in condensed films. While recent findings are mainly published in English, the foundational classical results were originally published in Russian, with limited accessibility to general readers. The present work is based on a 2019 Ukrainian monograph, "Temperature Stability of the Supercooled Liquid Phase in Condensed Films," which has been extensively revised and expanded. The book includes a detailed analysis of the thermodynamics of supercooled fluids, with updated and expanded sections. Additionally, new results on the supercooling of indium-lead (In-Pb) alloys in contact with amorphous molybdenum and fusible metals in contact with nanocrystalline layers are presented. These layers occupy a middle ground between amorphous (carbon, molybdenum, as-deposited germanium films) and polycrystalline (copper, silver, aluminum) substrates. The book gives particular attention to the peculiarities of contracted geometry conditions, which are natural for multilayered structures and can occur through fusible component segregation at grain boundaries. The analysis of new data has prompted a rethinking of the role of the more refractory layer's microstructure on the crystallization processes of metastable melts. The book includes a thorough discussion of these findings, highlighting the crucial role of the microstructure in the crystallization process. This book is a valuable resource for researchers and students interested in crystallization in thin-film metallic systems. This comprehensive study provides a detailed and authoritative analysis of the thermodynamics of supercooled fluids, and the impact of microstructure on the crystallization processes of metastable melts, making it an essential addition to any academic library.
