Book Description
Spin-based transport in semiconductor systems has been proposed as the foundation of a new class of spintronic devices. For the practical realization of such devices it is important to identify magnetic materials with diverse electronic transport properties (metallic, semiconducting, insulating) and sufficiently high Curie temperature (T_C) that can be readily integrated with standard semiconductors. Promising classes of materials for this purpose are the magnetic spinel oxides and chalcogenides. Some of these spinel-based materials are also attractive for biomedical applications. The facile solution-based synthesis of monodisperse nanocrystals of a wide variety of magnetic ferrites and nanocrystals of the chalcospinel CuCr_2 Se_4, along with their structural and magnetic properties, is presented in the first section of the dissertation. The following section presents a theoretical investigation of the electronic band structure of two quaternary chalcospinel systems, Cd_x Cu_1-x Cr_2 Se_4 and Cd_x Cu_1-x Cr_2 S_4, and also a number of anion-substituted Cr-based chalcospinels. A wide range of half-metal compositions are predicted both for the cation and anion substituted chalcospinels. The synthesis of spinels has been expanded to the growth of ferrites films using the direct liquid injection chemical vapor deposition (DLI-CVD) technique, which is detailed in the last section of the dissertation. High quality epitaxial NiFe_2 O_4 films have been grown using this technique with the magnetic properties of the films being comparable to those observed in the bulk, even for films grown at a high deposition rate. The growth of other thin film ferrites, such as lithium ferrite and barium hexaferrite, which are useful for higher frequency microwave applications are being investigated. The eventual goal is to use extend the DLI-CVD technique for the synthesis of chalcospinels films - in particular those predicted to be half-metallic - which have the potential for a variety of applications in spintronic devices.

Book Description
Spintronics manipulates individual magnetic moments to integrate logic functions and non-volatile information storage on the same platform. As is often the case in condensed matter science, advances are made through the synthesis of novel materials and high quality new physics materials. Giant magnetoresistance and dilute magnetic semiconductors are two such examples. However, the remarkable potential of spintronics for quantum computation faces major challenges when it comes to controlling simultaneously several qbits encoded in magnetic moments.After a brief introduction to concepts in nanomagnetism and spintronics, the text reviews recent techniques and their achievements in the synthesis and fabrication of magnetic nanostructures. The methods presented here emphasize bottom up or top down approaches for nanodots, nanowires and thin films. They include: focused ion beam irradiation, electron beam-induced chemical vapour deposition, chemical, and electrochemical methods. The later part of the book reviews magnetoelectric materials, the giant magnetoresistance in magnetic superlattices, dynamics effects in spin transfer torque oscillators, dilute magnetic oxides, rare earth nitrides with nuclear resonance scattering, and Mössbauer spectroscopy in spintronics. Finally, the last part of this book discusses applications to magnetic storage and bio-magnetism.Nanomagnetism and Spintronics will be useful to graduate students and researchers and engineers in the field of nanoscience.

Book Description
In early 1987 I was attempting to develop a CVD-based tungsten process for Intel. At every step ofthe development, information that we were collecting had to be analyzed in light of theories and hypotheses from books and papers in many unrelated subjects. Thesesources were so widely different that I came to realize there was no unifying treatment of CVD and its subprocesses. More interestingly, my colleagues in the industry were from many disciplines (a surface chemist, a mechanical engineer, a geologist, and an electrical engineer werein my group). To help us understand the field of CVD and its players, some of us organized the CVD user's group of Northern California in 1988. The idea for writing a book on the subject occurred to me during that time. I had already organized my thoughts for a course I taught at San Jose State University. Later Van Nostrand agreed to publish my book as a text intended for students at the senior/first year graduate level and for process engineers in the microelectronics industry, This book is not intended to be bibliographical, and it does not cover every new material being studied for chemical vapor deposition. On the other hand, it does present the principles of CVD at a fundamental level while uniting them with the needs of the microelectronics industry.

Book Description
This volume provides the first comprehensive look at a pivotal new technology in integrated circuit fabrication. For some time researchers have sought alternate processes for interconnecting the millions of transistors on each chip because conventional physical vapor deposition can no longer meet the specifications of today's complex integrated circuits. Out of this research, ionized physical vapor deposition has emerged as a premier technology for the deposition of thin metal films that form the dense interconnect wiring on state-of-the-art microprocessors and memory chips. For the first time, the most recent developments in thin film deposition using ionized physical vapor deposition (I-PVD) are presented in a single coherent source. Readers will find detailed descriptions of relevant plasma source technology, specific deposition systems, and process recipes. The tools and processes covered include DC hollow cathode magnetrons, RF inductively coupled plasmas, and microwave plasmas that are used for depositing technologically important materials such as copper, tantalum, titanium, TiN, and aluminum. In addition, this volume describes the important physical processes that occur in I-PVD in a simple and concise way. The physical descriptions are followed by experimentally-verified numerical models that provide in-depth insight into the design and operation I-PVD tools.
