Available in PDF, EPUB and Kindle. Book excerpt: During the last 20 years interest in high-resolution x-ray diffractometry and reflectivity has grown as a result of the development of the semiconductor industry and the increasing interest in material research of thin layers of magnetic, organic, and other materials. For example, optoelectronics requires a subsequent epitaxy of thin layers of different semiconductor materials. Here, the individuallayer thicknesses are scaled down to a few atomic layers in order to exploit quantum effects. For reasons of electronic and optical confinement, these thin layers are embedded within much thicker cladding layers or stacks of multilayers of slightly different chemical composition. It is evident that the interface quality of those quantum weHs is quite important for the function of devices. Thin metallic layers often show magnetic properties which do not ap pear for thick layers or in bulk material. The investigation of the mutual interaction of magnetic and non-magnetic layers leads to the discovery of colossal magnetoresistance, for example. This property is strongly related to the thickness and interface roughness of covered layers.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Flame technology is an extremely effective method to synthesize nano-particles of ceramic oxides. The single-step chemistry, the ability to control shape and size and to produce millions of tons of nano-powders per annum with relative ease have made it popular with industry. Although this process primarily focused on oxides of silicon and titanium, it has now been adopted for manufacture of several other oxides of bismuth, vanadium, aluminum, iron, germanium and zirconium. There has been extraordinary progress in the application of flame burner to synthesize newer oxides having a wide range of particle size, polydispersity, composition and aggregation. But the fundamentals behind the mechanisms for particle formation and growth are still not well understood. Due to the extremely fast reaction rates, high temperatures and low concentrations associated with this process, it is difficult to accurately observe the formation of nuclei and their growth to aggregated nano-particles. Entire particle growth from inception to aggregation takes place in a few milliseconds! Light scattering and thermophoretic sampling have been used extensively to study such flames. But light scattering suffers from the brightness of the flame and the limitation on the size-range it can probe. It can only detect aggregates, and information about primary particles needs to be obtained by thermophoretic sampling. However thermophoretic sampling is an intrusive technique and sample collection in the flame involves disturbance of flow of the gases and the particles in the flame. It is necessary to find a single non-intrusive technique that can yield complete information for the flame and detect the rapid growth. In-situ small angle x-ray scattering (iSAXS), which utilizes high energy x-rays from synchrotron sources fits such a role perfectly. iSAXS of particles in the flame provides full information from nano-scale to micron-scale and about the evolution of particles and their morphology. Experiments were carried out at third generation synchrotrons like Advanced Photon Source (USA) and European Synchrotron Radiation Facility (France). Several premixed and diffusion flames producing silica and titania were investigated for the product volume fraction, primary particle size, polydispersity of powders, number concentration, aggregate size, mass fractal dimension and degree of branching.

Annual Subcontract Report, February 1, 1992--January 31, 1993 written by and published by . This book was released on 1994 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our general objectives are to provide new details of the microstructure for the size scale from about 1 to 30 nm in high-quality a-Si:H and related alloys prepared by current state-of-the-art deposition methods as well as by new and emerging deposition technologies and thereby help determine the role of microvoids and other density fluctuations in controlling the opto-electronic properties. More specifically, the objectives are to determine whether the presence of microstructure as detected by small-angle x-ray scattering (SAXS) (1) limits the photovoltaic properties of device-quality a-Si:H, (2) plays a role in determining the photo-stability of a-Si:H, and (3) is responsible for degradation of the photovoltaic properties due to alloying with Ge, C and other constituents. The approach involves collaboration with several groups that can supply relevant systematic sets of samples and the associated opto-electronic data to help address these issues. Since the SAXS technique has not been a standard characterization technique for thin-film materials, and was recently set up at CSM with support by NREL, the project involves considerable development of the method with regard to standardizing the procedures, minimizing substrate influences and implementing improved data reduction and modeling methodology. Precise, highly reproducible, and accurate results are being sought in order to allow useful, reliable, and sensitive comparisons of materials deposited under different conditions, by different methods, and by different systems that represent the same nominal method.

Download or read book X-Ray Compton Scattering written by Malcolm Cooper and published by OUP Oxford. This book was released on 2004-10-14 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the development of potent x-ray sources at many synchrotron laboratories worldwide, Compton scattering has become a standard tool for studying electron densities in materials. This book provides condensed matter and materials physicists with an authoritative, up-to-date, and very accessible account of the Compton scattering method, leading to a fundamental understanding of the electrical and magnetic properties of solid materials. The spectrum of Compton scattered x-rays is particularly sensitive to this behaviour and thus can be used as a direct probe and to test the predictions of theory. The current generation of synchrotron facilities allows this method to be readily exploited to study the ground state electron density in both elements and in complex compounds. It is important that those working in related fields, as well as the increasing number directly using the Compton method, have a comprehensive assessment of what is now possible and how to achieve it, in addition to a full understanding of its theoretical basis. This monograph is unique and timely, since little of what is described, was practicable a decade ago. The development of synchrotron radiation facilities has ensured that the technique described here will remain a powerful probe of electron charge and spin density for many years to come.

This book was released on 2013-03-09 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: energy production, environmental management, transportation, communication, computation, and education. As the twenty-first century unfolds, nanotechnology's impact on the health, wealth, and security of the world's people is expected to be at least as significant as the combined influences in this century of antibiotics, the integrated circuit, and human-made polymers. Dr. Neal Lane, Advisor to the President for Science and Technology and former National Science Foundation (NSF) director, stated at a Congressional hearing in April 1998, "If I were asked for an area of science and engineering that will most likely produce the breakthroughs of tomorrow, I would point to nanoscale science and engineering. " Recognizing this potential, the White House Office of Science and Technology Policy (OSTP) and the Office of Management and Budget (OMB) have issued a joint memorandum to Federal agency heads that identifies nanotechnology as a research priority area for Federal investment in fiscal year 2001. This report charts "Nanotechnology Research Directions," as developed by the Interagency W orking Group on Nano Science, Engineering, and Technology (IWGN) of the National Science and Technology Council (NSTC). The report incorporates the views of leading experts from government, academia, and the private sector. It reflects the consensus reached at an IWGN-sponsored workshop held on January 27-29, 1999, and detailed in contributions submitted thereafter by members of the V. S. science and engineering community. (See Appendix A for a list of contributors.
