Available in PDF, EPUB and Kindle. Book excerpt: Although there has been steady progress in understanding aspects of epitaxial growth throughout the last 30 years of modern surface science, work in this area has intensified greatly in the last 5 years. A number of factors have contributed to this expansion. One has been the general trend in surface science to tackle problems of increasing complexity as confidence is gained in the methodology, so for example, the role of oxide/metal interfaces in determining the properties of many practical supported catalysts is now being explored in greater detail. A second factor is the recognition of the potential importance of artificial multilayer materials not only in semiconductor devices but also in metal/metal systems because of their novel magnetic properties. Perhaps even more important than either of these application areas, however, is the newly-discovered power of scanning probe microscopies, and most notably scanning tunneling microscopy (STM), to provide the means to study epitaxial growth phenomena on an atomic scale under a wide range of conditions. These techniques have also contributed to revitalised interest in methods of fabricating and exploiting artificial structures (lateral as well as in layers) on a nanometre scale. This volume, on Growth and Properties of Ultrathin Epitaxial Layers, includes a collection of articles which reflects the present state of activity in this field. The emphasis is on metals and oxides rather than semiconductors.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This work was motivated and focused on the growth mechanism, microstructures and interfaces of barium titanate, BaTiO3 (BTO), based epitaxial thin films. Transimission electron microscopy (TEM), high resolution TEM (HRTEM), electron diffraction (ED) have been mainly employed in this study for microstructure investigations of BTO-based epitaxial thin films with the assistance of other materials characterization methods, such as X-ray diffraction (XRD), atomic force microscopy (AFM), Nanoindentation testing, etc. As a basic studying model, epitaxial BTO films were first deposited on the (001) MgO substrate using RF magnetron sputtering to provide fundamental knowledge of the film growth for BTO based thin films. The epitaxial BTO films show a tetragonal crystal structure (a = 4.02 Å and c = 4.11 Å) with epitaxial nanodomains induced from the rough film/substrate interface due to the modification of the substrate surface characteristics (steps, terraces, and kinks) during the deposition process. Two new phases of - calculus [gamma]y (Ba10TiO26) and Hß (BaTi8O24) were formed on the MgO substrate using RF magnetron sputtering. The atomic structures of the two new phases were determined and examined. The [gamma]y phase has a monoclinic structure, Cm, a=16.49 Å̊̊, b=8.94 Å, c=3.94 Å, y=77°. The Hß phase has a monoclinic structure, Cm, a = 17.88̊Å̊, b = 7.21Å, c = 3.94 Å̊̊̊, y =82°. Both [gamma]y and Hß phases have four different oriented domains. The orientation relationship between domains and MgO substrate is discussed. Initail study shows that these new phases possess novel and interesting properties. The doped BTO films with different dopant (Sr2 and Zr4) fabricated using pulsed laser deposition (PLD) have been studied for doping effects, interface effects and film growth mechanism. The (Ba, Sr)TiO3 (BST) epitaxial films grown on 1.2° and 5.3° miscut substrates consist of lager commensurate domains, and correspondly show higher dielectric constant and dielectric tunability, and lower average modulus and hardness than those of the films grown on the 3.5° miscut substrate. The results suggest that the differences on the interfacial structure have a tremendous effect on the properties of the films. The investigation on epitaxial Ba(Zr, Ti)O3 (BZT) and 2% Mn doped Ba(Zr, Ti)O3 (Mn:BZT) thin films grown on MgO substrate revealed the formation of twin-coupled domains on the epilayer by sharing their {111}/{110} planes as common planes. The structure evolution from epilayer to nanopillars is accomplished by alternatively introducing {111} and {110} twin boundaries, resulting in gradual shrinking or enlarging of the lateral size of the epitaxial grains/twin coupled nanopillars. The formations of twin domains, sharing planes and structure transition mechasim have been discussed in detail. Eventually, the microstructures and layer interfaces of [Mn:BZT//Mn:BST]N multilayer films consisting of 2% Mn doped (Ba, Sr)TiO3 (Mn:BST) and Mn:BZT layers on MgO (001) substrates with various deposition rates, deposition period numbers N were studied to provide an integral view of the formation of multilayer films in BTO system. All the [Mn:BZT//Mn:BST]N multilayer films present epitaxial quality and induced {111}/{110} twin-coupled domains initially formed at different film thickness/layers. The film/substrate interface has an important role for the formation of twin domains and the proportion of twin domain structures in the entire films. The layer interfaces between Mn:BST and Mn:BZT with period compression and extension strains were observed and discussed. The microstructure evolution and structure-related nano-mechanical properties of the multilayer films have been systematically investigated.

Available in PDF, EPUB and Kindle. Book excerpt: In December 2002, the world's first commercial magnetic levitation super-train went into operation in Shanghai. The train is held just above the rails by magnetic levitation (maglev) and can travel at a speed of 400 km/hr, completing the 30km journey from the city to the airport in minutes. Now consumers are enjoying 50 GB hard drives compared to 0.5 GB hard drives ten years ago. Achievements in magnetic materials research have made dreams of a few decades ago reality. The objective of the four volume reference, Handbook of Advanced Magnetic Materials, is to provide a comprehensive review of recent progress in magnetic materials research. Each chapter will have an introduction to give a clear definition of basic and important concepts of the topic. The details of the topic are then elucidated theoretically and experimentally. New ideas for further advancement are then discussed. Sufficient references are also included for those who wish to read the original work. In the last decade, one of the most significant thrust areas of materials research has been nanostructured magnetic materials. There are several critical sizes that control the behavior of a magnetic material, and size effects become especially critical when dimensions approach a few nanometers, where quantum phenomena appear. The first volume of the book, Nanostructured Advanced Magnetic Materials, has therefore been devoted to the recent development of nanostructured magnetic materials, emphasizing size effects. Our understanding of magnetism has advanced with the establishment of the theory of atomic magnetic moments and itinerant magnetism. Simulation is a powerful tool for exploration and explanation of properties of various magnetic materials. Simulation also provides insight for further development of new materials. Naturally, before any simulation can be started, a model must be constructed. This requires that the material be well characterized. Therefore the second volume, Characterization and Simulation provides a comprehensive review of both experimental methods and simulation techniques for the characterization of magnetic materials. After an introduction, each section gives a detailed description of the method and the following sections provide examples and results of the method. Finally further development of the method will be discussed. The success of each type of magnetic material depends on its properties and cost which are directly related to its fabrication process. Processing of a material can be critical for development of artificial materials such as multilayer films, clusters, etc. Moreover, cost-effective processing usually determines whether a material can be commercialized. In recent years processing of materials has continuously evolved from improvement of traditional methods to more sophisticated and novel methods. The objective of the third volume, Processing of Advanced Magnetic Materials, is to provide a comprehensive review of recent developments in processing of advanced magnetic materials. Each chapter will have an introduction and a section to provide a detailed description of the processing method. The following sections give detailed descriptions of the processing, properties and applications of the relevant materials. Finally the potential and limitation of the processing method will be discussed. The properties of a magnetic material can be characterized by intrinsic properties such as anisotropy, saturation magnetization and extrinsic properties such as coercivity. The properties of a magnetic material can be affected by its chemical composition and processing route. With the continuous search for new materials and invention of new processing routes, magnetic properties of materials cover a wide spectrum of soft magnetic materials, hard magnetic materials, recording materials, sensor materials and others. The objective of the fourth volume, Properties and Applications of Advanced Magnetic Materials, is to provide a comprehensive review of recent development of various magnetic materials and their applications. Each chapter will have an introduction of the materials and the principles of their applications. The following sections give a detailed description of the processing, properties and applications. Finally the potential and limitation of the materials will be discussed.
