International Series of Monographs on Semiconductors, Volume 8: Structure and Application of Galvanomagnetic Devices focuses on the composition, reactions, transformations, and applications of galvanomagnetic devices. The book first ponders on basic physical concepts, design and fabrication of galvanomagnetic devices, and properties of galvanomagnetic devices. Discussions focus on changes in electrical properties on irradiation with high-energy particles, magnetoresistor field-plate, Hall generator, preparation of semiconductor films by vacuum deposition, structure of field-plate magnetoresistors, growth of semiconductors from the melt, and galvanomagnetic materials and effects. The text then elaborates on the applications of the Hall effect and the magnetoresistance effect. Topics include contactless control, connecting the field-plate to other semiconductor devices, non-contacting variable resistance and potentiometer, measurement of magnetic fields and quantities proportional to magnetic fields, and measurement of quantities representable by a magnetic induction. The manuscript underscores other possibilities for controlling the electrical properties of semiconductors by means of a magnetic field. The publication is a vital source of data for researchers wanting to explore the structure and applications of galvanomagnetic devices.

Eukaryotic cells contain a plurality of organelles distinguished by their specific membranes and contents. Their biogenesis occurs by growth and division of preexisting structures rather than de novo. Mitochondria and chloroplasts, which appear to be descended from prokaryotic ancestors, have retained some DNA and the biosynthetic capability for its expression. They synthesize, however, only a few of their proteins themselves. Most of their proteins are synthesized on free ribosomes in the cytoplasm and are only assembled in the correct membrane after synthesis is complete. The biogenesis of peroxisomes and glyoxysomes also appears to occur by an incorporation of proteins synthesized first in the cytoplasm. Other organelles, the Golgi complex, lysosomes, secretory vesicles, and the plasma membrane, are formed in a different manner. Their proteins are assembled in the membrane of the endoplasmic reticulum during trans lation by bound ribosomes and they must then be transported to the correct membrane. The 1980 Mosbach Colloquium was one of the first attempts to discuss the biogenesis of the various organelles in biochemical terms. This was appropriate since the crucial problems now center on the search for signals and receptors that dictate the site of assembly, the route taken, and the final location of a particular organelle protein. The assembly of prokaryotic membranes and the membrane of an animal virus were also discussed, since these simpler systems might shed light on the biogenesis of organelles in eukaryotes.

Innerhalb von etwa 20 Jahren seit dem Erscheinen der ersten integrier ten Schaltungen auf dem Markt erreicht die MOS-Technik heute den höchsten Grad der Integration in der Halbleitertechnik. Die Gründe für diese stürmische Entwicklung sind neben der Möglichkeit, MOS-Tran sistoren sehr dicht zu packen. auch das einfache Prinzip und der ein fache Aufbau des MOS-Transistors. Der Zweck dieses Buches ist es, einen Oberblick über die MOS-Technik sowie die mit ihr verbundenen Möglichkeiten zu geben. Es wendet sich gleichermaßen an den Technologen wie an den Schaltungs ingenieur , die gemeinsam eine integrierte Schaltung entwickeln und herstellen. Mit steigendem Integrationsgrad wird es jedoch möglich, ganze Systeme auf dem Chip zu integrieren. Das Buch wendet sich daher auch an den Systemarchitekten , der eine Schaltung konzipiert, und der über die technologischen und schaltungstechnischen Grundlagen Bescheid wissen sollte, da die Voraussetzung zum Gelingen eines hochkomplexen VLSI Schaltkreises die Kenntnis der Probleme des Partners ist. Das Buch wendet sich aber auch an Studenten der Physik, der Elektro technik und der Informatik, die sich neu in das Gebiet der integrierten MOS-Schaltungen einarbeiten wollen. Besonders für sie werden daher nach einer eingehenden Betrachtung des MOS-Kondensators die Grund struktur des MOS-Transistors sowie die aus diesem abgeleiteten Bau elemente beschrieben. Die Herstellungstechniken sowie die dabei auf tretenden Probleme werden erläutert. Anschließend werden die Schal tungstechniken von integrierten MOS-Schaltungen und ihre Entwurfs techniken eingehend behandelt. 6 Den Herren E. Musil, R. Hezel, N. Lieske, H. Klar und H.-J.
