This book was released on 2014-06-05 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: A wide variety of materials systems and deposition strategies have been developed to produce epitaxial and polycrystalline thin films. In particular, controlling the morphology and microstructure of metal films at the nanometer and/or micron scale has become crucial for applications such as giant magnetoresistive devices, contacts and diffusion barriers in integrated circuits and photovoltaics, and multilayer X-ray mirrors. This book, first published in 2001, focuses on the interactions between different mechanisms of microstructure evolution and film-growth conditions. Two sections of the volume, including a joint effort with Symposium R, Morphology and Dynamics of Crystal Surfaces in Molecular and Colloid Systems, highlight the fundamental mechanisms of epitaxial growth. Additional topics include: multilayers - stress in thin films; early stages of film growth - mechanical properties; texture in polycrystalline films; grain growth - barrier layers; and silicides and organic thin films - pulsed laser deposition.

Book Synopsis Mechanisms for Intrinsic Stress Evolution During and After Polycrystalline Film Growth by : Hang Yu (Ph. D.)
Download or read book Mechanisms for Intrinsic Stress Evolution During and After Polycrystalline Film Growth written by Hang Yu (Ph. D.) and published by . This book was released on 2013 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growth of polycrystalline films involves poorly understood kinetic processes that occur far from equilibrium and lead to complex co-evolution of the surface, microstructure and intrinsic stress of the films. Here we present a comprehensive study consisting of in situ stress measurements, microstructure characterization, and analytical modeling for various polycrystalline systems. We find that in systems of high atomic mobility, the stress change after polycrystalline film growth can be attributed to a fast reversible surface process and a slow irreversible bulk process. The fast process is weakly dependent on temperature and is associated with changes in the shape of grain surfaces. The slow process is strongly dependent on temperature and is mostly associated with grain growth in the bulk of the film. We also discovered a turnaround phenomenon in which, under conditions of intermediate atomic mobility, the stress evolves from a tensile toward a compressive state, and then turns around to evolve toward a tensile state. This stress turnaround phenomenon is strongly dependent on the substrate temperature and deposition rate, and can be attributed to an increase of the grain size during film deposition. Grain growth during deposition not only leads to a tensile component of the intrinsic stress, but also changes the grain size dependence of the compressive component. The compressive component results from incorporation of excess adatoms in grain boundaries, and the magnitude of the compressive stress is controlled by a competition between adatom incorporation in 2D islands and incorporation at grain boundaries. We also investigated the effect of the angle of incidence of the flux of depositing atoms on stress and structure evolution during polycrystalline film growth. We find that as the angle of incidence increases, the coalescence thickness increases and the stress becomes less compressive or more tensile. We attribute these phenomena to the enhanced surface roughness, the shadowing effect, the steering effect and the presence of Ehrlich-Schwoebel barriers during oblique angle deposition. All these effects lead to suppression of the adatom-grain boundary incorporation process. Based on this thesis work, intrinsic stresses in polycrystalline films can be categorized into three types: Type I, the intermediate type and Type II. These behaviors are observed in systems of low, intermediate and high atomic mobility, respectively. Compressive stresses develop in Type II behavior and tensile stresses develop in Type I behavior. The transition of the stress behavior from Type I, to the intermediate type and to Type II is continuous and can be achieved by adjusting deposition conditions. Whether the post-coalescence stress is tensile, or compressive, or evolving from compressive to tensile depends on the homologous temperature, the deposition rate and the angle of the incidence of the flux of depositing atoms.
Book Synopsis Substrate Surface Structure Effects on Microstructure of Epitaxial Films by :
Download or read book Substrate Surface Structure Effects on Microstructure of Epitaxial Films written by and published by . This book was released on 1992 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microstructure of epitaxial thin films grown on sapphire substrates using the metal organic chemical vapor deposition technique were found to depend on the substrates surface structure. Epitaxial TiO[sub 2] films grown on the sapphire (0001) substrates were highly-oriented polycrystal and the films on the (1120) substrates were single crystal. First-principles total energy calculations were carried out to gain atomistic understandings of sapphire surface structures and their effects on microstructure of epitaxial films. The surface terminating atom planes were found to be Al atoms for the (0001) surface and O atoms for the (1120). Minimum step heights were one sixth of the lattice constant c for the (0001) and one half of the lattice constant a for the (1120). Steps of minimum height or its odd multiples on sapphire (0001) surface double the number of variants in the deposited films. The symmetry and step of the substrate surface and symmetry of the epitaxial growth plane controlled the microstructure of the epitaxial films.

Book Synopsis Pulsed Laser Ablation by : Ion N. Mihailescu
Download or read book Pulsed Laser Ablation written by Ion N. Mihailescu and published by CRC Press. This book was released on 2018-01-09 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pulsed laser–based techniques for depositing and processing materials are an important area of modern experimental and theoretical scientific research and development, with promising, challenging opportunities in the fields of nanofabrication and nanostructuring. Understanding the interplay between deposition/processing conditions, laser parameters, as well as material properties and dimensionality is demanding for improved fundamental knowledge and novel applications. This book introduces and discusses the basic principles of pulsed laser–matter interaction, with a focus on its peculiarities and perspectives compared to other conventional techniques and state-of-the-art applications. The book starts with an overview of the growth topics, followed by a discussion of laser–matter interaction depending on laser pulse duration, background conditions, materials, and combination of materials and structures. The information outlines the foundation to introduce examples of laser nanostructuring/processing of materials, pointing out the importance of pulsed laser–based technologies in modern (nano)science. With respect to similar texts and monographs, the book offers a comprehensive review including bottom-up and top-down laser-induced processes for nanoparticles and nanomicrostructure generation. Theoretical models are discussed by correlation with advanced experimental protocols in order to account for the fundamentals and underline physical mechanisms of laser–matter interaction. Reputed, internationally recognized experts in the field have contributed to this book. In particular, this book is suitable for a reader (graduate students as well as postgraduates and more generally researchers) new to the subject of pulsed laser ablation in order to gain physical insight into and advanced knowledge of mechanisms and processes involved in any deposition/processing experiment based on pulsed laser–matter interaction. Since knowledge in the field is given step by step comprehensively, this book serves as a valid introduction to the field as well as a foundation for further specific readings.
