Book excerpt: The impact of Materials Science in our environment has probably never been as massive and decisive as it is today. In every aspect of our lives, progress has never been so dependent on the techniques involved in producing ever more sophisticated materials in ever larger quantities, nor so demanding for technologists to imagine novel processes and circumvent difficulties, or take up new challenges. Every technique is based on a physical process which is put into practice and optimized. The better we know that process, the better the optimization, and more powerful the technique. Laser processing of materials is inscribed in that context. As soon as powerful coherent light sources were made available, it was realized that such intense sources of energy could be used to "heat, melt and crystallize" materials, i.e., to promote phase transitions in atomic systems. As early as 1964, attempts in that direction were made but received very little (if any) attention. Reasons for this lack of interest were several. For one thing, laser technology was not fully developed, so that the process offered poor reliability and no versatility. Also, improving the existing techniques was believed to be sufficient to meet the needs of the time, and there was no real motivation to explore new ways. Finally, and more important, the fundamentals of the physics behind the scenes were, and continue to be, way out of the runni~g stream.

Download or read book Interfaces Under Laser Irradiation written by L.D. Laude and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: Known and developed over the past twenty five years, lasers have been experimented in a variety of processes with an uneven success. Apart from fundamental physics experiments in which the various aspects of coherence are systematically exploited, applications in the field of Materials Science have been scattered recently over so many situations that it is apparently difficult today to conceive a comprehensive interpretation of all physical processes encountered. In some domains of research like photochemistry, development has been fast and rather self-supporting. In others, like solid-state processing, progress has been either very specific or deviated towards marginal applications, or else emerged as a joint-venture between physicists and chemists. This yielded a number of professional meetings, where day-to-day research activities are presented. In 1982, the Cargese ASI on "Cohesive properties of semiconductors under laser irradiation" was one of such meetings at which a prospective of the field was discussed at length in ebullient round-table sessions. Quoted from the proceedings, "the Institute helped to discern clearly the limits of existing theoretical approaches and the directions along which work is urgently needed within the next few years". Four years have passed and the field has literally explo ded. It must be mentioned that some of the most striking developments over the past two years were accurately predicted at the Institute in Cargese.

Book Synopsis Surface Processing and Laser Assisted Chemistry by : E. Fogarassy
Download or read book Surface Processing and Laser Assisted Chemistry written by E. Fogarassy and published by Elsevier. This book was released on 1990-12-01 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: The papers in this volume cover all aspects of laser assisted surface processing ranging from the preparation of high-Tc superconducting layer structures to industrial laser applications for device fabrication. The topics presented give recent results in organometallic chemistry and laser photochemistry, and novel surface characterization techniques. The ability to control the surface morphology by digital deposition and etching shows one of the future directions for exciting applications of laser surface processing, some of which may apply UV and VUV excitation. The understanding of elementary proceses is essential for the design of novel deposition methods, with diamond CVD being an outstanding example. The high quality of these contributions once again demonstrates that the E-MRS is an efficient forum for interaction between research workers and industry.

The book also elucidates the screening effects involved in the exciton-plasma transition; the optical bistability and nonlinearity; and experimental techniques with short pulse spectroscopy. Other topics emphasized are the physical aspects of laser annealing and of melting at the highest excitation levels, as well as the results of high excitation and short pulse physics of quantum wells. The fast relaxation processes, as well as the carrier-carrier and carrier-phonon interactions are also explained. This material will serve as a source of information and reference, and will stimulate ways for further research.
Book Synopsis Confined Electrons and Photons by : Elias Burstein
Download or read book Confined Electrons and Photons written by Elias Burstein and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 900 pages. Available in PDF, EPUB and Kindle. Book excerpt: The optical properties of semiconductors have played an important role since the identification of semiconductors as "small" bandgap materials in the thinies, due both to their fundamental interest as a class of solids baving specific optical propenies and to their many important applications. On the former aspect we can cite the fundamental edge absorption and its assignment to direct or indirect transitions, many-body effects as revealed by exciton formation and photoconductivity. On the latter aspect, large-scale applications sucb as LEDs and lasers, photovoltaic converters, photodetectors, electro-optics and non-linear optic devices, come to mind. The eighties saw a revitalization of the whole field due to the advent of heterostructures of lower-dimensionality, mainly two-dimensional quantum wells, which through their enhanced photon-matter interaction yielded new devices with unsurpassed performance. Although many of the basic phenomena were evidenced through the seventies, it was this impact on applications which in turn led to such a massive investment in fabrication tools, thanks to which many new structures and materials were studied, yielding funher advances in fundamental physics.
Book Synopsis Modern Crystallography III by : A.A. Chernov
Download or read book Modern Crystallography III written by A.A. Chernov and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: Early in this century, the newly discovered x-ray diffraction by crystals made a complete change in crystallography and in the whole science of the atomic structure of matter, thus giving a new impetus to the development of solid-state physics. Crystallographic methods, pri marily x-ray diffraction analysis, penetrated into materials sciences, mol ecular physics, and chemistry, and also into many other branches of science. Later, electron and neutron diffraction structure analyses be came important since they not only complement x-ray data, but also supply new information on the atomic and the real structure of crystals. Electron microscopy and other modern methods of investigating mat ter-optical, electronic paramagnetic, nuclear magnetic, and other res onance techniques-yield a large amount of information on the atomic, electronic, and real crystal structures. Crystal physics has also undergone vigorous development. Many re markable phenomena have been discovered in crystals and then found various practical applications. Other important factors promoting the development of crystallog raphy were the elaboration of the theory of crystal growth (which brought crystallography closer to thermodynamics and physical chem istry) and the development of the various methods of growing synthetic crystals dictated by practical needs. Man-made crystals became increas ingly important for physical investigations, and they rapidly invaded technology. The production . of synthetic crystals made a tremendous impact on the traditional branches: the mechanical treatment of mate rials, precision instrument making, and the jewelry industry.
