Book Description
Low-dimensional materials are of fundamental interest in physics and chemistry and have also found a wide variety of technological applica tions in fields ranging from microelectronics to optics. Since 1986, several seminars and summer schools devoted to low-dimensional systems have been supported by NATO. The present one, Physics, Fabrication and Applications of Multilayered structures, brought together specialists from different fields in order to review fabrication techniques, charac terization methods, physics and applications. Artificially layered materials are attractive because alternately layering two (or more) elements, by evaporation or sputtering, is a way to obtain new materials with (hopefully) new physical properties that pure materials or alloys do not allow. These new possibilities can be ob tained in electronic transport, optics, magnetism or the reflectivity of x-rays and slow neutrons. By changing the components and the thickness of the layers one can track continuously how the new properties appear and follow the importance of the multilayer structure of the materials. In addition, with their large number of interfaces the study of inter face properties becomes easier in multilayered structures than in mono layers or bilayers. As a rule, the role of the interface quality, and also the coupling between layers, increases as the thickness of the layer decreases. Several applications at the development stage require layer thicknesses of just a few atomic layers.

Book Description
The first in its field, this book is both an introduction to x-ray lasers and a how-to guide for specialists. It provides new entrants and others interested in the field with a comprehensive overview and describes useful examples of analysis and experiments as background and guidance for researchers undertaking new laser designs. In one succinct volume, X-Ray Lasers collects the knowledge and experience gained in two decades of x-ray laser development and conveys the exciting challenges and possibilities still to come. The reader is first introduced to the technical challenges unique to the design and operation of lasers in the "vacuum" region of the spectrum, where the atmosphere is highly absorbent and optics are--at best--unconventional. A discussion of the basic principles for and limitations in achieving significant x-ray amplification, as well as descriptions of gain measurement techniques and instrumentation follows. Various approaches for pumping media to x-ray gain conditions are also analyzed, and descriptions of experimental progress are included wherever possible. The book concludes with a description and comparison with alternate sources and applications for an x-ray laser. This work is both an introduction to x-ray lasers and a how-to guide for specialists. It provides new entrants and others interested in the field with a comprehensive overview and describes useful analyses and experiments as guidance for researchers undertaking new laser designs. - Provides first comprehensive treatment of lasers for wavelengths shorter than the near-ultraviolet 2000 - Contains descriptions and comparisons with alternate sources - Includes a section describing possible applications
