Book Description
This report discusses the ways in which H2 enters steels, how it moves through steel, and methods whereby it may be removed from steel. The solubility of H2 is important in understanding other aspects of the behavior of H2 in steel and such aspects of solubility as preferred lattice sites, lattice expansion, measurements of solubility, and estimates of equilibrium H2 pressure in steel are discussed. The permeation of H2 through steel consisting of interactions at both the entry and exit surfaces of the metal as well as diffusion through the bulk metal is discussed. The various possibilities of H2 entry by corrosion processes, electrochemical processes, and other means are considered as well as factors which influence the rate of H2 removal from iron and steel.

Book Description
Auger electron spectroscopy is rapidly developing into the single most powerful analytical technique in basic and applied science.for investigating the chemical and structural properties of solids. Its ex plosive growth beginning in 1967 was triggered by the development of Auger analyzers capable of de tecting one atom layer of material in a fraction of a second. Continued growth was guaranteed firstly by the commercial availability of apparatus which combined the capabilities of scanning electron mi croscopy and ion-mill depth profiling with Auger analysis, and secondly by the increasing need to know the atomistics of many processes in fundamental research and engineering applications. The expanding use of Auger analysis was accompanied by an increase in the number of publications dealing with it. Because of the developing nature of Auger spectroscopy, the articles have appeared in many different sources covering diverse disciplines, so that it is extremely difficult to discover just what has or has not been subjected to Auger analysis. In this situation, a comprehensive bibliography is obviou-sly useful to those both inside and outside the field. For those in the field, this bibliography should be a wonderful time saver for locating certain references, in researching a particular topic, or when considering various aspects of instrumentation or data analysis. This bibliography not only provides the most complete listing of references pertinent to surface Auger analysis available today, but it is also a basis for extrapolating from past trends to future expectations.

Book Description
Hydrogen on semiconductor surfaces has been an area of considerable activity over the last two decades. Structural, thermal, and dynamical properties of hydrogen chemisorbed on crystalline silicon and other semiconductors have been studied in great detail. These properties serve as a reference for related, but more complex systems such as hydrogen at multiple vacancies in crystalline semiconductors or at microvoids in amorphous samples. Interesting from a surface physics point of view is the fact that hydrogen as a monovalent element is an ideal terminator for unsaturated bonds on surfaces and therefore tends to have a large influence on surface reconstruction. A related phenomenon with large technological impact (for example in low cost solar cells) is the passivation of grain boundaries in microcrystalline semiconductors. Finally, hydrogenated semiconductor surfaces always appear as a boundary layer during low-energy hydrogenation of bulk semiconductors, so that a complete description of hydrogen uptake or desorption necessarily has to take these surfaces into account. This collection of invited and contributed papers has been carefully balanced to deal with amorphous and crystalline semiconductors and surfaces and presents basic and experimental work (basic and applied) as well as theory. The resulting volume presents a summary of the state-of-the-art in the field of hydrogen in semiconductors and will hopefully stimulate future work in this area.
