Ion Implantation in Semiconductors and Other Materials (The IBM Research Symposia Series)

by Billy Crowder

During the years since the first conference in this series was held at Thousand Oaks, California, in 1970, ion implantation has been an expanding and exciting research area. The advances in this field were so rapid that a second conference convened at Garmisch­ Partenkirchen, Germany, in 1971. At the present time, our under­ standing of the ion implantation process in semiconductors such as Si and Ge has reached a stage of maturity and ion implantation techniques are firmly established in semiconductor device technology. The advances in compound semiconductors have not been as rapid. There has also been a shift in emphasis in ion implanta­ tion research from semiconductors to other materials such as metals and insulators. It was appropriate to increase the scope of the conference and the IIIrd International Conference on Ion Implanta­ tion in Semiconductors and Other Materials was held at Yorktown Heights, New York, December 11 to 14, 1972. A significant number of the papers presented at this conference dealt with ion implanta­ tion in metals, insulators, and compound semiconductors. The International Committee responsible for organizing this conference consisted of B. L. Crowder, J. A. Davies, F. H. Eisen, Ph. Glotin, T. Itoh, A. U. MacRae, J. W. Mayer, G. Dearnaley, and I. Ruge. The Conference attracted 180 participants from twelve countries. The success of the Conference was due in large measure to the financial support of our sponsors, Air Force Cambridge Research Laboratories and the Office of Naval Research.

Laplace-Transformation: Lehrbuch für Elektrotechniker u. Physiker ab 5. Sem. (uni-texte)

by James G. Holbrook

VI sprechen. Er ist der Meinung, daß sich mit der Zeit herausstellen wird, in welchem Ausbildungsstadium die Theorie der Laplace-Transformation ge­ boten werden sollte, um maximale Wirkung zu erzielen. Im Gegensatz zur "stationl!.ren" Ll:lsung, die man mit Hilfe der klassi­ schen Netzwerkanalyse unter Benutzung des j-Operators erhl!.lt, gestattet die Theorie der Laplace-Transformation eine vollstl!.ndige Analyse von Problemen in elektronischen Schaltungen. Der Leser ml:lge sich in Erinne­ rung rufen, daß die AusdrUcke "induktive Reaktanz" und "kapazitive Reak­ tanz" nur dann einen Sinn haben, wenn wir von einer strikt sinusfl:lrmigen Erregung sprechen. Sie bleiben sinnlos, wenn wir es mit einer der vielen anderen heute benUtzten Schwingungsformen zu tun haben. Daraus ist er­ sichtlich, wie notwendig es ist, zumindest eine gewisse Spanne Zeit dem Studium allgemeiner Methoden und Denkwege zu widmen. Die Laplace­ Transformation ist eine allgemeine Methode. Sie gestattet, Netzwerke zu analysieren, in denen beliebige Schwingungsformen auftreten.

Lectures on Electrochemical Corrosion

by Marcel Pourbaix

Workers in the field of corrosion and their students are most fortunate that a happy set of circumstances brought Dr. Marcel Pourbaix into their field in 1949. First, he was invited, while in the USA, to demonstrate at a two­ week visit to the National Bureau of Standards the usefulness of his electro­ chemical concepts to the study of corrosion. Secondly, also around the same time, Prof. H. H. Uhlig made a speech before the United Nations which pointed out the tremendous economic consequences of corrosion. Because of these circumstances, Dr. Pourbaix has reminisced, he chose to devote most of his efforts to corrosion rather than to electrolysis, batteries, geology, or any of the other fields where, one might add, they were equally valuable. This decision resulted in his establishing CEBELCOR (Centre BeIge d'Etude de la Corrosion) and in his development of a course at the Free University of Brussels entitled "Lectures on Electrochemical Corrosion." This book is the collection of these lectures translated into English.

The Light of the Night Sky (Episteme #8)

by F. E. Roach

Astronomy appears to us as a combination of art, science, and philosophy. Its study puts the universe into perspective, giving a sense of pleasure in its beauty, awe at its immensity, and humility at our trivial place in it. From earliest human history, man has scrutinized the night sky - and wondered and marveled. With unaided eye but perceptive mind, he recognized order in the regular appearance and movements of individual objects, such as the planets and star groups (constellations), in their rhythmic and majestic progressions across the bowl of night. Even in the present era of scientific exactitude, there remains a profound awareness of mysteries beyond our present interpretations. It is only in comparatively recent years, however, that man has recognized that it takes more than conventional astronomy to account for the beauties ofthe night sky. Radiations in the Earth's upper atmosphere provide a foreground light, the study of which has come under a new name, aeronomy. The science of aeronomy has rapidly burgeoned, and the student of the light of the night sky finds that he is involved in an interdisciplinary domain.

Limnology of a Small Malayan River Sungai Gombak (Monographiae Biologicae #22)

by J. Bishop

Rivers are recognized as major natural resources, not only as sources of domestic, industrial and agricultural water and hydro-electric power, but also for food production and increasingly for recreation and tourist promotion. This awareness has led to increased study of lotic limnology, particularly with respect to the development of the potentials of river systems. The concern over deterioration of watercourses as a result of poor land utilization and their use as repositories for man's rejectamenta has stimulated research into the basic dynamics of the river environment and its biotic communities. Before any assessment of pollution effects can be made, or rational remedial action suggested, there must be a sound, detailed knowledge of the 'natural' characteristics of regional water­ courses as a reference standard. This knowledge can result only from investigating the whole drainage area as a unit ecosystem (E VANS 1956) rather than just the specific conditions in the river itself (cf. SLACK 1955, HYNES 1969). Biotic data for any stream are of little value if divorced from consideration of the geology, hydrochemistry, land use and nutrient cycles of the watershed that generated them. The study of large rivers, potamobiology in the sense of I LLIES (1955, 1961 a), is a specialized area of research merging into lenitic ecology in many aspects and cannot be considered here.

Literature 1972, Part 2 (Astronomy and Astrophysics Abstracts #8)

by S. Böhme W. Fricke U. Güntzel-Lingner F. Henn D. Krahn U. Scheffer G. Zech

Astronomy and Astrophysics Abstracts, which has appeared in semi-annual volumes since 1969, is de­ voted to the recording, summarizing and indexing of astronomical publications throughout the world. It is prepared under the auspices of the International Astronomical Union (according to a resolution adopted at the 14th General Assembly in 1970). Astronomy and Astrophysics Abstracts aims to present a comprehensive documentation of literature in all fields of astronomy and astrophysics. Every effort will be made to ensure that the average time interval between the date of receipt of the original literature and publication of the abstracts will not exceed eight months. This time interval is near to that achieved by monthly abstracting journals, com­ pared to which our system of accumulating abstracts for about six months offers the advantage of greater convenience for the user. Volume 8 contains literature published in 1972 and received before March 15, 1973; some older liter­ ature which was received late and which is not recorded in earlier volumes is also included.

Logic, Language, and Probability: A Selection of Papers Contributed to Sections IV, VI, and XI of the Fourth International Congress for Logic, Methodology, and Philosophy of Science, Bucharest, September 1971 (Synthese Library #51)

by Radu J. Bogdan and Ilkka Niiniluoto

The Fourth International Congress for Logic, Methodology, and Philos­ ophy of Science was held in Bucharest, Romania, on August 29-September 4, 1971. The Congress was organized, under the auspices of the Inter­ national Union for History and Philosophy of Science, Division of Logic, Methodology and Philosophy of Science, by the Academy of the Socialist Republic of Romania, the Academy of Social and Political Sciences of the Socialist Republic of Romania, and the Ministry of Education of Romania. With more than eight hundred participating scholars from thirty-four countries, the Congress was one of the major scientific events of the year 1971. The dedicated efforts of the organizers, the rich and carefully planned program, and the warm and friendly atmosphere contributed to making the Congress a successful and fruitful forum of exchange of scientific ideas. The work of the Congress consisted of invited one hour and half-hour addresses, symposia, and contributed papers. The proceedings were organized into twelve sections of Mathematical Logic, Foundations of Mathematical Theories, Automata and Programming Languages, Philos­ ophy of Logic and Mathematics, General Problems of Methodology and Philosophy of Science, Foundations of Probability and Induction, Methodology and Philosophy of Physical Sciences, Methodology and Philosophy of Biological Sciences, Methodology and Philosophy of Psychological Sciences, Methodology and Philosophy of Historical and Social Sciences, Methodology and Philosophy of Linguistics, and History of Logic, Methodology and Philosophy of Science.

Luminescence of Crystals, Molecules, and Solutions: Proceedings of the International Conference on Luminescence held in Leningrad, USSR, August 1972

by Ferd Williams

These Proceedings report the scholarly work presented in Leningrad at the largest conference ever held on luminescence. In addition to the large number of delegates, the Conference was dis­ tinguished by strong and balanced representation on the program of papers from capitalist and socialist nations. The Conference was sponsored by the International Union of Pure and Applied Physics and by the Academy of Science of the USSR. As noted in the Opening Ceremony, this Conference is in the series held approximately every three years since 1938. All branches of luminescence are included. It was recognized, during the early stages of organization of the Conference, that there would be difficulties associated with the preparation of an English version of the Proceedings. Until just before the Conference, it was not evident whether translations of the Russian papers would be available and whether facilities would exist at the Conference for a working publication committee to edit the manuscripts. It was not possible, therefore, to make contractual arrangements before the Conference for publication.

The Many Worlds Interpretation of Quantum Mechanics (Princeton Series in Physics #63)

by Bryce Seligman Dewitt Neill Graham

A novel interpretation of quantum mechanics, first proposed in brief form by Hugh Everett in 1957, forms the nucleus around which this book has developed. In his interpretation, Dr. Everett denies the existence of a separate classical realm and asserts the propriety of considering a state vector for the whole universe. Because this state vector never collapses, reality as a whole is rigorously deterministic. This reality, which is described jointly by the dynamical variables and the state vector, is not the reality customarily perceived; rather, it is a reality composed of many worlds. By virtue of the temporal development of the dynamical variables, the state vector decomposes naturally into orthogonal vectors, reflecting a continual splitting of the universe into a multitude of mutually unobservable but equally real worlds, in each of which every good measurement has yielded a definite result, and in most of which the familiar statistical quantum laws hold. The volume contains Dr. Everett's short paper from 1957, "'Relative State' Formulation of Quantum Mechanics," and a far longer exposition of his interpretation, entitled "The Theory of the Universal Wave Function," never before published. In addition, other papers by Wheeler, DeWitt, Graham, and Cooper and Van Vechten provide further discussion of the same theme. Together, they constitute virtually the entire world output of scholarly commentary on the Everett interpretation.Originally published in 1973.The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
