Surface Treatment V : Computer Methods and Experimental Measurements

Product Description
The use of surface treatments can not only reduce the cost of expensive components employed in critical applications but also extend the useful lifetime of existing structural elements or increase the load carrying capacity for the same life. In recent years, they have therefore received considerable attention from the engineering and scientific community.

This book contains edited versions of most of the papers presented at the Fifth International Conference on Computer Methods and Experimental Measurements for Surface Treatment Effects. The aim of these meetings is to encourage international co-operation amongst scientists, technologists and engineers and to assist in a better understanding of areas such as fatigue, fracture and wear resistance.

Throughout the volume particular emphasis is given to the application of advanced theories and experimental techniques. The contributions come from internationally acknowledged researchers working in this multidisciplinary field and are divided under the following headings: Changing Material Properties; Corrosion; Damage, Fatigue and Fracture Mechanics; Laser Surface Treatment; Residual Stress Effect; Shot Peening; Surface Coating; and Thermal Processes.

Point-Contact Spectroscopy

Product Description
The physical principles of spectroscopy of quasi-particle excitations in metals at low temperatures by means of point contacts are presented. The point contact constitutes a tiny metallic bridge connecting bulk electrodes. The spectroscopic regime corresponding to the contact dimensions range from only a few to tens of nanometers. For contacts larger than the inelastic electron free mean path the thermal regime holds. Along with most thoroughly studied phono excitations, the interaction of electrons with other quasiparticles (magnons, crystal-field electron excitations, paramagnetic impurities, two-level systems, etc), are reviewed. Various experimental techniques for point contact production are described, and many examples of point -contact spectra are presented for pure metals, alloys and compounds, as well as for semimetals and semiconductors, heavy fermion systems, Kond-lattices, mixed valence compounds and so forth. Superconducting point contacts are considered in respect to Andreev reflection and Josephson effects. Special attention is paid to contact conductance fluctuation, are regarded as well as new trends of research are outlined.

Mesoscopic Electronics in Solid State Nanostructures

Product Description
This text treats electronic transport in the regime where conventional textbook models are no longer applicable, including the effect of electronic phase coherence, energy quantization and single-electron charging. This second edition is completely updated and expanded, and now comprises new chapters on spin electronics and quantum information processing, transport in inhomogeneous magnetic fields, organic/molecular electronics, and applications of field effect transistors. The book also provides an overview of semiconductor processing technologies and experimental techniques. With a number of examples and problems with solutions, this is an ideal introduction for students and beginning researchers in the field.

“This book is a useful tool, too, for the experienced researcher to get a summary of recent developments in solid state nanostructures. I applaud the author for a marvellous contribution to the scientific community of mesoscopic electronics.”
—Prof. K. Ensslin, Solid State Physics Laboratory, ETH Zurich

Cluster Beam Synthesis of Nanostructured Materials

Product Description
The book gives a systematic description of the preparation , characterization and manipulation of cluster beams for the synthesis of nanocrystalline materials. It also addresses all the issues relevant in the realization of nanophase structures (cluster-surface interaction, cluster coalescence). The book provides a complete description of the method with the major aim of offering a working tool for scientists coming from different fields. Particular emphasis is given to the potential of this technique in connection with the synthesis of nanostructured materials and to the combination of cluster beams with other surface science experimental techniques. The question of the compatibility with more standard technologies will also be addressed.
