Available in PDF, EPUB and Kindle. Book excerpt: The book reviews the most interesting research concerning the radiation defects formed in 6H-, 4H-, and 3C-SiC under irradiation with electrons, neutrons, and some kinds of ions. The electrical parameters that make SiC a promising material for applications in modern electronics are discussed in detail. Specific features of the crystal structure of SiC are considered. It is shown that, when wide-bandgap semiconductors are studied, it is necessary to take into account the temperature dependence of the carrier removal rate, which is a standard parameter for determining the radiation hardness of semiconductors. The carrier removal rate values obtained by irradiation of various SiC polytypes with n- and p-type conductivity are analyzed in relation to the type and energy of the irradiating particles. The influence exerted by the energy of charged particles on how radiation defects are formed and conductivity is compensated in semiconductors under irradiation is analyzed. Furthermore, the possibility to produce controlled transformation of silicon carbide polytype is considered. The involvement of radiation defects in radiative and nonradiative recombination processes in SiC is analyzed. Data are also presented regarding the degradation of particular SiC electronic devices under the influence of radiation and a conclusion is made regarding the radiation resistance of SiC. Lastly, the radiation hardness of devices based on silicon and silicon carbide are compared.

Available in PDF, EPUB and Kindle. Book excerpt: This book brings together the most up-to-date information on the fabrication techniques, properties, and potential applications of low dimensional silicon carbide (SiC) nanostructures such as nanocrystallites, nanowires, nanotubes, and nanostructured films. It also summarizes the tremendous achievements acquired during the past three decades involving structural, electronic, and optical properties of bulk silicon carbide crystals. SiC nanostructures exhibit a range of fascinating and industrially important properties, such as diverse polytypes, stability of interband and defect-related green to blue luminescence, inertness to chemical surroundings, and good biocompatibility. These properties have generated an increasing interest in the materials, which have great potential in a variety of applications across the fields of nanoelectronics, optoelectronics, electron field emission, sensing, quantum information, energy conversion and storage, biomedical engineering, and medicine. SiC is also a most promising substitute for silicon in high power, high temperature, and high frequency microelectronic devices. Recent breakthrough pertaining to the synthesis of ultra-high quality SiC single-crystals will bring the materials closer to real applications. Silicon Carbide Nanostructures: Fabrication, Structure, and Properties provides a unique reference book for researchers and graduate students in this emerging field. It is intended for materials scientists, physicists, chemists, and engineers in microelectronics, optoelectronics, and biomedical engineering.

This book was released on 1991 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Type C SiC whiskers showed a more obvious toughening effect for Si$\sb3$N$\sb4$ ceramics than the commercial Tokamax SiC whiskers. This might be due to the effect of interfacial bonding and/or the effect of the morphology and size of the whiskers.

Available in PDF, EPUB and Kindle. Book excerpt: Various electron microscopy techniques have been used to evaluate the microstructural and interfacial characteristics of silicon carbide whisker-reinforced alumina composites. The effects of subjecting whiskers to oxidizing and reducing treatments prior to composite fabrication were examined. Whisker/matrix interfaces in which carbon coatings were applied to whiskers prior to specimen fabrication were also examined. Physical and thermodynamic arguments can be used to explain why it is difficult to greatly modify the physical nature of the whisker/matrix interface. 7 refs., 7 figs.

This book was released on 2004-02-20 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetically engineered organisms (GEOs) have been under development for more than 20 years while GE crops have been grown commercially during the last decade. During this time, a number of questions have cropped up concerning the potential consequences that certain GEOs might have on natural or managed ecosystems and human health. Interest in developing methods to confine some GEOs and their transgenes to specifically designated release settings has increased and the success of these efforts could facilitate the continued growth and development of this technology. Biological Confinement of Genetically Engineered Organisms examines biological methods that may be used with genetically engineered plants, animals, microbes, and fungi. Bioconfinement methods have been applied successfully to a few non-engineered organisms, but many promising techniques remain in the conceptual and experimental stages of development. This book reviews and evaluates these methods, discusses when and why to consider their use, and assesses how effectively they offer a significant reduction of the risks engineered organisms can present to the environment. Interdisciplinary research to develop new confinement methods could find ways to minimize the potential for unintended effects on human health and the environment. Need for this type of research is clear and successful methods could prove helpful in promoting regulatory approval for commercialization of future genetically engineered organisms.
